thunar crashed with SIGSEGV

[David Kastrup]

Not sure what other bug this may be equal to. Crashed while exploring folders, possibly in connection with SDcard in a USB reader (Expresscard size factor, Sony VGP-MCA20).

Right click on any unmounted volume in left tree panel make thunar to crash.

Arch linux 64 bits updated.
xfce4 and thunar updated.

Thanks for reporting !

I cannot reproduce this bug. Does it always happen for you, or just rarely ?

Does the crash happen for all kind of volumes ? How did you mount / unmount it ?

Could you please try to generate a backtrace with debug symbols ? ( Without symbols it is almost useless )
Here some distro-specific how to: https://docs.xfce.org/contribute/bugs/start

Yes, the crash happens with all UNMOUNTED partitions, volumes (connected hard disk, ssd), MTP device(android) and usb pendrives, when I click with right mouse button on them. Only unmounted ones that shows the tree view

I guess this regression was introduce by this commit:
https://git.xfce.org/xfce/thunar/commit/?id=cb12bc1

We should not rely on _thunar_return_val_if_fail or g_return_val_if_fail for NULL check, those macros are only meant for debugging.
