Artur, these are crashes which were happening on your device for the last 2 days and which you mentioned in a different issue but crash logs were not yet available. I've reviewed them now and I tried to fix them. I say tried as crash reports were not very clear what in fact caused a crash. I've seen that a lot of threads were waiting on the same variable, so I've queued this tasks for a single thread instead of blocking many threads.

I'll release a new build soon. Please check if this issue is gone or if the application is still crashing.

I cannot close the ticket because I have not experienced crashes related to roster view. At least from my end-user point of view. So I cannot verify if this problem is fixed.

My crashes were related to chat list view and opening a chat.

Then I'm closing this task because I've seen crash reports for them and I do not see them anymore.
