Bug 323406

Saved a perspective Assistant to default location (/home/user/documents)
Close the assistant and trying to load it results in crashing. Same after reopen krita with a new
document. Same with OpenGL turned on or off.

No Crash with other Assistant Tools.

Reproducible: Always




Application: Krita (kdeinit4), signal: Aborted
