Public bug reported:
1) Running AMD64 edition of Ubuntu 20.04.2 LTS; it is up-to-date with no
pending updates from the main repo.
2) Specifically, have the amd64 build of gnome-control-center
1:3.36.5-0ubuntu2 installed. libgdk-pixbuf2.0-0 is version
2.40.0+dfsg-3ubuntu0.2, libcairo2 is 1.16.0-4ubuntu1, libgtk2.0-0 is
2.24.32-4ubuntu4 and libgtk-3-0 is 3.24.20-0ubuntu1.
3) What I expected to happen: possible to navigate between the
"Applications" and other tabs of the Control Center without a crash.
4) What happens (100% reproducibly) instead: if the Control Center
starts in any view except Applications, clicking on "Applications" in
the selection pane causes an immediate application crash (hard exit)
with the text below written to stderr. When the Control Center is
restarted, the Applications pane is now loaded, and can be navigated as
expected until I click the "<" in the top left of the window (to go back
and select another category), whereupon it immediately crashes with the
same error message quoted below.
Error message written to stderr in either case above:
Gdk-ERROR **: 22:18:27.542: The program 'gnome-control-center' received an X
Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
(Details: serial 47249 error_code 11 request_code 130 (MIT-SHM) minor_code 5)
From the backtrace below, it looks like this is possibly related to
loading the pixmap for one of my application icons; I happen to have
several applications with broken/missing icons (all Steam games), but
don't have any problems viewing or starting those games from the
Launcher, nor navigating to their settings when gnome-control-center
launches in the Applications view (e.g. after the crash described above,
or by manual selection on the command line). In any event, a Control
Center crash for a missing or corrupted pixmap is not robust behavior.
Of note, line #14 in the backtrace (gdk_window_create_similar_surface) shows a
"height" parameter of 43972, which may be unreasonably large in comparison to
the width of 242 and possibly contributing to the BadAlloc. This machine has
16GB of RAM and no issues running much more demanding applications than the
Control Center.
