well, you guys are not alone, i hijacked a thread last month and posted my woes there Skin is broken after each reboot since July update - #10 by wildkard
i found a workaround but the crashing (90% of the time i log off) was so random, i had to actually roll back to a raspbmc+xbmc gotham config.
Til this is resolved, i’m stuck in 2013.
