[Alexey A Nikitin]

Package: libgtkmm-3.0-1v5

Severity: grave

Dear Maintainer,

I attempted to launch GParted and saw it crash immediately after initially showing its window
I attempted to delete all /root/.gtkrc*, /root/.config/gtkrc*, and /root/.config/gtk-3.0/settings.ini
files, as I had configured Breeze as GTK theme and I thought maybe that has something to do with the crash
since console does spam theme-related warning messages. That did visibly reset the GTK theme for GParted,
but the crash was still there.

I'm also attaching the core dump from the run before my attempt to reset GTK theme.
