Segfault when adding a new task

[hackel]

So, this is strange. I haven't touched my build of TimeIT in ages, but upgrading one of its dependencies recently must have triggered this. Whenever I try to create a new task (either root or sub-task), TimeIT segfaults. I have tried doing this with a fresh ~/.config/TimeIT directory with the same result.

Thread 1 "timeit" received signal SIGSEGV, Segmentation fault.

Sorry for slow response.

What operating system and version?

[Hoglet]

This is probably triggered by a change in the window manager. If the window manager does not return the same number of workspace/desktop names as is actual existing then TimeIT crashes.

I have confirmed this behaviour in Gnome-shell. This probably means that the Mutter window manager also causes this problem.
