Hi,
boinc always crashes when it starts; I can provide my /var/lib/boinc-
client dir if this is needed to reproduce.
I've installed boinc-dbg now and ran boinc in gdb. Looking at the stack
backtrace the problem seems to be related to long paths inside the .wine
directory (didn't even know boinc uses wine):
