Sometimes randomly krita crashes when apply a transformation most probably rotation. this has happened 5 times out of 10 for me . Fortunately this time the bug report wizard popped up so i could get a back trace from it , I don't know it it will help Reproducible: Always Steps to Reproduce: 1.try to transform something with ctrl + t 2.hit enter to apply the transformation Actual Results: krita crashes Expected Results: the transformation should be applied as normal I will try to keep an eye on this bug and provide more information regarding this for now this si the back trace I got from the bug report wizard Application: krita (krita), signal: Aborted Using host libthread_db library "/usr/lib/libthread_db.so.1".

The crash looks really weird. What size of the image you have?
I am closing this as i haven't encountered this in new git builds. If i encounter them in future i'll make new bug reports for now the issue seems to be resolved
I am encountering this bug again hence i am opening this , krita now randomly crashes close to 4-5 times while transforming below is the bug trace generated by bug report wizard Application: krita (krita), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
