A few weeks ago, Gimp was working fine, then I tried to open it, the icon flashes away a bit, and then closes again, one time there appeared a dialog which told me that Gimp had unexpectedly closed, and I could choose wether I wanted to restart the program or leave it closed. Restarting had no effect.
Then I started Gimp via terminal, and got this output:

Segmentatiefout (geheugendump gemaakt)
The last half are errors from a theme I had installed.
I have tried reinstalling, purging the installation via terminal and via Synaptic, but I still get the same result.
Running Ubuntu 16.04 LTS
