OpenBoard crashes when right-clicking on a text box

[I027614]

OpenBoard (both 1.5.4 and 1.6.1 versions) on Linux (Mageia 8, x-64) crashes when right-clicking on a text box.

From console:

openboard
libpng warning: iCCP: known incorrect sRGB profile
Persisting document; path is "/home/katnatek/.local/share/OpenBoard/document/OpenBoard Document 2021-04-19 21-34-45.133/metadata.rdf"

Cannot reproduce that on openSUSE.

Which package did you install? Where did you download the package?

I installed https://rpmfind.net/linux/mageia/distrib/8/x86_64/media/core/release/openboard-1.5.4-5.mga8.x86_64.rpm from Mageia repositories.

Hi,

I'm the Mageia maintainer of openboard package and I confirm that it segfault for us after right-clicking on the text box.

I tried the latest 1.6.1 release without success it also segfault, so here attached the full backtrace:

Here our package structure for Cauldron:
http://svnweb.mageia.org/packages/cauldron/openboard/current/

And the one for mageia 8:

Thanks, but this looks really strange to me: the complete traceback does not contain a single "UBxxx" class, only Qt classes are referenced (besides the main application). Seems to happen during the delivery of the right-click event to a widget through all those Qt internal classes. Also the this pointer looks ok to me. So currently I have no further ideas...

Have you tested as this attached screenshot?

Just like that (even the same text). It crashes when right-clicking in the text box. :-(

Hi,

thanks for reporting this. I quickly checked and It's also happening on the official release on the three platforms...

Seems reported, and fixed : https://bugreports.qt.io/browse/QTBUG-88309, or maybe it's another one.

Please use the key shortcuts until he fix is available, as it seems the issue is related to the context menu.

EDIT : ok maybe it's on the Qt 5.15.3 release that is only available for users with a commercial licence...

Confirmed rebuilding qtbase 5.15.2 with QTBUG-88309 patch fixes this text box issue!

Thanks a lot @kaamui

The bug appeared with Qt 5.15.1 so compiling with 5.15.0 binaries also works.
