Crash with Gtk error when trying to open directory chooser

[gxtu]

When I try to open the directory chooser, the program crashes with the following error message:

(BlobBackup:177022): Gtk-WARNING **: 21:10:18.384: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.
**
Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Paper/16x16/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3)
Bail out! Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Paper/16x16/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3)
zsh: abort (core dumped)  ./BlobBackup

Steps to reproduce:

1. Download, extract and launch BlobBackup version linux_amd64_v1.0.0.beta2 from the Github releases page
2. Open the creation dialog for a new backup
3. Select "Local Directory" as the storage location
4. Click "Browse" next to the directory input

This is on ArchLinux. It only happens with the packaged release. When I run it directly from source, it works fine. I'm using a Gtk icon theme (Paper) and the image file mentioned in the error message exists and doesn't appear to be corrupted. Running update-mime-database /usr/share/mime or gdk-pixbuf-query-loaders --update-cache didn't fix the problem. It might be related to PyInstaller, which seems to have had similar issues in the past.

@gxtu Welcome to the project and thanks for reporting!

Pyinstaller works pretty well for Windows and OSX but I've had trouble getting it to work reliably across different Linux distros. I'm considering making BlobBackup an installable pip package and removing the pre-packaged binary from the releases page just for Linux. It would resolve this issue and other similar distro specific issues from coming up.

When I run it directly from source, it works fine.

Just to confirm, when you run from source, everything works as you expect on Arch right?

Yes, that is correct.

Made a new issue for the PyPi package. Will leave this open until we resolve that one

Hey @gxtu, I just merged https://github.com/bimbashrestha/BlobBackup/pull/28 which makes BlobBackup a pip package. Can you try:

$ python setup.py develop
$ blobbackup

from the dev branch on your Arch and see if you get this crash still?

[gxtu]

I just tried

$ python -m venv env
$ source env/bin/activate
$ pip install --upgrade pip
$ pip install wheel
$ python setup.py develop

which gives me the following error: error: The 'google-auth' distribution was not found and is required by google-auth-oauthlib. Trying to run blobbackup anyway results in ModuleNotFoundError: No module named 'shiboken2' (which is probably because it aborted before installing all dependencies).

Using pip install . instead of python setup.py develop does work though and lets me use BlobBackup and the directory chooser as expected.

Thanks for testing.

Hmm, not sure why the google-auth distribution can't be found. Strange. In any case, I think pip install . is preferable to python setup.py install/develop since you can uninstall more easily.

I'll upload the package to PyPi at some point and recommend that Linux users just install using pip in the docs. Going to close this for now but feel free to leave more comments.
