Comment 21 for bug 1064195

I installed debuginfo packages now and attached gdb to udisksd, I get the following backtrace:
Program received signal SIGABRT, Aborted.
[Switching to Thread 0x7fa21ffff700 (LWP 2865)]
0x00007fa230cae849 in raise () from /lib64/libc.so.6

So it seems to assert in udiskslinuxfilesystem.c:623, which is:
gassert (block == NULL);
