Subject: fuse: Fix segfault in guestmount --verbose.
X-Git-Tag: 1.7.20~11
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=97cbb842362e2548a59a1560c50e5f998fa5bda8;p=libguestfs.git

fuse: Fix segfault in guestmount --verbose.

If hash_delete returns NULL and --verbose option was given then
this would cause a segfault.
