#42 Crash in file open dialog

[Jesse Litton]

To recreate, I simply hit ctrl-O and select any directory in the file open dialog:

Bail out! Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /org/gtk/libgtk/icons/16x16/status/image-missing.png: Couldn?t allocate memory for loading PNG (gdk-pixbuf-error-quark, 1)
Aborted (core dumped)

I build from source using the supplied makefile. There were zero warnings or errors on the build. This is on Ubuntu 19.10 with the most current libgdk-pixbuf2 packages installed.

Also, the memory allocation message is spurious. The 32GB system RAM and 8GB video RAM are each under half used and the message still appears.

I thought this might be due to a missing icon in the GTK theme I have set for my Plasma desktop. So, I changed the GTK icon theme to oxygen. Yet, the problem persists.

I can see it's at least finding the right file now when I do an strace:

openat(AT_FDCWD, "/usr/share/icons/oxygen/base/16x16/status/image-missing.png", O_RDONLY) = 37

The /usr/share/icons/oxygen/base/16x16/status/image-missing.png file opens fine from any other app.

I've verified the same thing happens if I pick a different theme, which also has a 16x16/status/image-missing.png icon.

stat("/usr/share/icons/hicolor/index.theme", {st_mode=S_IFREG|0644, st_size=55507, ...}) = 0

Same here running the binary release on Ubuntu 19.10.

Yes, this is an odd error in the GTK when custom event loop is created and this also varies between GTK versions. To overcome this temporarily you can select "Use system dialogs ON/OFF" in the settings menu which is a workaround for this error.

[slajerek]

This has been fixed in latest version 0.64.56.8. Please confirm and reopen if this is still an issue.

@slajerek I'm still seeing this with 0.64.56.8:

I have the same problem. The temporary solution ("Use system dialogs ON/OFF") stops the crashing, but when I enter the folder I want to set to drive 8, there's no option to actually set that directory to Drive 8. How do I do this?
