Binary package hint: libsmbclient

In latest 8.10, I find that when using a filesystem mounted with fusesmb, the filesystem will suddenly disappear. This is very repeatable and does seem to be load related although more experimenting will be needed to find the exact cause.

Each time it happens, I get a line in my log:

Oct 29 10:02:57 gort kernel: [69797.713426] fusesmb[16090]: segfault at 4 ip b7c03590 sp b5514dc0 error 4 in libsmbclient.so.0[b7b88000+386000]
Oct 29 11:00:01 gort kernel: [73221.338081] fusesmb[20089]: segfault at 4 ip b7cc9590 sp b55dadc0 error 4 in libsmbclient.so.0[b7c4e000+386000]

I've tried to get a backtrace with gdb, having installed fusesmb-dbgsym and libsmbclient-dbgsym but I can't seem to get it to attach properly. I'm a total noob with gdb, but I've tried "set follow-fork-mode child" and "set debug lin-lwp 1" but nothing seems to do the trick. I've asked around but to no avail, so if any deb could tell me how to supply a backtrace (or any other info you need) I'll be glad to oblige.

By the way, should apport pick this crash up, or not?
