Bug#886665: Can not view files inside a commercial audio CD-ROM

[Andreas Henriksson]

Hello Gilles CHARABOT,

Thanks for the backtrace. I'll start with a few observations:

You're running gvfs 1.34.1-2.

Crash (assertion failure) seems to happen when the volume_mount_cb
function calls into g_proxy_volume_mount_finish which leads us to
g_simple_async_result_propagate_error.

Earlier in the backtrace we're coming from g_task_return_now
so we're definitely mixing g_task with G_simple_async_result
which as smcv already explained it a bad mix.

I'm not sure exactly where the problem is initiated or introduced
but given that there where so GTask changes introduced in
1.33.3 I'd guess this might be where the problem was introduced:
https://git.gnome.org/browse/gvfs/commit/?id=2eae1086656ebfa1b8eb

Further GTask porting has been done in the development releases
after the stable version currently in debian, and the fix is
likely to already be available in them. More exactly I expect this
commit to fix your particular issue:
https://git.gnome.org/browse/gvfs/commit/?id=1f5fcbe8d7b8a2975ef
The above commit together with several other GTask related commits
are part of 1.35.3.

It would be great if you could provide feedback if the newer version
fixes your issue, either once it's available in Debian Experimental
or if you could update the package yourself in the meantime.

HTH.

Regards,
Andreas Henriksson
