[Pkg-xfce-devel] Bug#800723: intermittent segfault on file drag and drop

[Javier Cantero]

Package: thunar
Version: 1.6.10-2
Followup-For: Bug #800723

Dear Maintainer,

I found the same error here. When I try to cut and paste a pair of files
into a subdirectory, Thunar crashes:

    $ /usr/bin/Thunar 

    (Thunar:7281): GLib-GObject-WARNING **: invalid uninstantiatable type '(null)' in cast to 'GObject'

    (Thunar:7281): GLib-GObject-CRITICAL **: g_object_set_qdata: assertion 'G_IS_OBJECT (object)' failed

    (Thunar:7281): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
    *** Error in `/usr/bin/Thunar': malloc(): smallbin double linked list corrupted: 0x0000561632084230 ***
    Aborted

Not every run shows the same final error message:

    $ /usr/bin/Thunar 

    (Thunar:7290): GLib-GObject-WARNING **: invalid uninstantiatable type '(null)' in cast to 'GObject'

    (Thunar:7290): GLib-GObject-CRITICAL **: g_object_set_qdata: assertion 'G_IS_OBJECT (object)' failed

    (Thunar:7290): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
    *** Error in `/usr/bin/Thunar': munmap_chunk(): invalid pointer: 0x000055a982e4f7e0 ***
    Aborted

Sometimes it's a segmentation fault:

    $ /usr/bin/Thunar 

    (Thunar:7296): GLib-GObject-WARNING **: invalid uninstantiatable type '<invalid>' in cast to 'GObject'

    (Thunar:7296): GLib-GObject-CRITICAL **: g_object_set_qdata: assertion 'G_IS_OBJECT (object)' failed

    (Thunar:7296): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

    (Thunar:7296): GLib-GIO-CRITICAL **: g_file_query_info: assertion 'G_IS_FILE (file)' failed



    (Thunar:7296): GLib-GIO-CRITICAL **: g_file_get_basename: assertion 'G_IS_FILE (file)' failed
    Segmentation fault

And sometimes Thunar doesn't crash at first try. Here I had to repeat
the operation before I got the crash:

    $ /usr/bin/Thunar 

    (Thunar:7316): GLib-GObject-WARNING **: invalid uninstantiatable type '(null)' in cast to 'GObject'

    (Thunar:7316): GLib-GObject-CRITICAL **: g_object_set_qdata: assertion 'G_IS_OBJECT (object)' failed
    Segmentation fault

It has to be some recent change because I didn't see this behaviour
until today.
