[Pkg-electronics-devel] Bug#948626: kicad: Closing pcbnew hangs main kicad process

[Paul "LeoNerd" Evans]

Package: kicad
Version: 5.1.5+dfsg1-2
Severity: normal

I can open, use and close eeschema just fine. I can open and use pcbnew
just fine, but when I attempt to close it and return back to the main
toplevel kicad window, the entire process hangs at 100% CPU usage, not
drawing any windows (existing onscreen content gets corrupted). It
remains in this state until SIGINT or SIGTERM.

If run from the terminal there is no printed output of any kind.

Connecting to a process in this state with gdb shows:

  $ gdb --pid 309563
