LO 5 keeps crashing

After upgrading from Build ID: 4.4.5.2 Arch Linux build-2 to LO5 the
program keeps crashing when trying to use certain functions such as text
color selection or inserting pictures or clip-art. But with many other
activities too.

I removed previous profiles and removed any data left after installing
4.4.5. Although, it seems there are still some hidden files left in the
system that are reused by LO5 after installing.

I have downgraded to 4.4.5 again because it is really frustrating to
have to restart the program every 2~5 minutes.

does anybody have an idea how I can solve this problem?

Cheers
