SIGSEGV in g_string_append_uri_escaped

[thierry-FreeBSD]

Hello,

I ported corebird-0.9 to FreeBSD. It builds without any problem.
I run it, then click on "Request PIN", and it aborts (segfault):

Program received signal SIGSEGV, Segmentation fault.
0x0000000803fdc08f in g_string_append_uri_escaped () from /usr/local/lib/libglib-2.0.so.0

A backtrace is available at https://gist.github.com/thierry-FreeBSD/adeab235d2e00ac9537e#file-gistfile1-txt

Previously, it displays:
account_get_screen_name: assertion 'IS_ACCOUNT (self)' failed

Any idea? Have you already seen this bug on other platforms?

Best regards.

Since you ported it yourself, can you compile it with --enable-debug (I hope this problem is reproducible?) It seems to be a problem in librest though, what version of it do you have (and... can you compile that with debugging symbols? :))

Yes, you're right, hereunder is a more detailed backtrace:

I have just submitted a bug report about our librest port:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197599

[baedert]

So we can close this here since it seems to be an upstream librest (or a port) bug?

[thierry-FreeBSD]

Yes, please do!
