Comment 1 Paweł 2016-07-19 18:24:36 UTC 
Now when I unlock my sd card It work as should. I used micro sd adapter with lock.
Comment 2 Andrius Štikonas 2016-07-19 18:36:19 UTC 
Hmm, this crash in Partition::sectorsUsed() is probably the same as all these other crashes reported in bugzilla which I unfortunately hasn't been able to reproduce. I can try to see if locking sd card would help.

Check if fileSystem pointer is nullptr before trying to read used space

Hopefully it fixes the following crashes as well:
