-- Information about the crash:
Sometimes *only when Firefox and Xournal++* are opened if I fold my device and plasma goes into touch mode I get this crash (also both the mentioned applications crash but for example other applications such as dolphin file manager doesn't)

The crash can be reproduced sometimes.
