Thunar crashes if the bookmarks list contains non-folder/non-directory

Step 1: find some GTK2 (such as Audacious) that can open a file chooser window
Step 2: open a file chooser window, and drag any sort of file that is NOT a directory/folder, into the Places list of the file chooser, so it puts it as a shortcut in the list of bookmarked places
Note that Thunar instantly crashes, and from then on crashes instantly when you try to run it:

free(): invalid pointer
Aborted (core dumped)

Does this happen for anyone else?

Well, I don't have a spare VM to try, so i'm not going to risk instant persistent crashes of my file manager right now, sorry!

Anyone with a disposable VM out there?

Also, for debugging purposes, please add version numbers of the apps involved, OS, etc... c'mon, of course!

Re: Thunar crashes if the bookmarks list contains non-folder/non-directory

When audacious opens the file chooser dialog, it is using GTK's FileChooser, not thunar. @dusthillresident, are you saying that thunar (which at this point is not involved in this transaction) is crashing? Or are you dragging from thunar into the FileChooser window?

Do you have anything in your log files (~/.xsession-errors) at the time of the crash?

Also, I'm not sure which distro you are using, but if it is systemd-based, what does:

coredumpctl list --no-pager

...say right after the crash?

Re: Thunar crashes if the bookmarks list contains non-folder/non-directory

it says this

TIME                            PID   UID   GID SIG COREFILE  EXE
Sun 2021-11-07 13:08:45 GMT  479575  1000  1000   6 present   /usr/bin/thunar
Sun 2021-11-07 13:08:47 GMT  480039  1000  1000   6 present   /usr/bin/thunar

I'm running ubuntu 21.04
I recorded this video to demonstrate: https://www.youtube.com/watch?v=kKe_jHnEqDI

So basically, Thunar seems to crash if you put non-directory items in the bookmarks/'places' list. Normally it's not possible to do it with thunar or the gtk3 file chooser, but it seems like the gtk2 file chooser has a bug where you can put anything in the bookmarks just by dragging it there.

Re: Thunar crashes if the bookmarks list contains non-folder/non-directory

Which gtk2 app is that ("choose music"), that you are using to get the GtkFileChooser dialog?

Can you post back the results of:

coredumpctl info 480039 --no-pager

Also, what version of thunar?

thunar -V

It's quite possible there is a thunar bug that that isn't handling the situation. There were some recent bookmark fixes in thunar that might have fixed the issue.

thunar 4.16.6 (Xfce 4.16)

I tried it with two different apps, "richard bannister's audio overload", and Audacious which is in ubuntu and debian's repos.

Re: Thunar crashes if the bookmarks list contains non-folder/non-directory

You'll need to install the thunar-dbgsym package so you can get true thunar debug info in that backtrace. To do so, you can follow the instructions here: https://wiki.ubuntu.com/Debug%20Symbol%20Packages.

Once installed, re-start the computer and generate the crash again. Then look at the backtrace as above. You will probably need to create a bug report at the bug tracker.

Note: I installed xubuntu 21.04 in a VM and tried to replicate the issue. Although it doesn't crash on my system, I end up with a blank non-functional entry in thunar.
