to create a backtrace in such a deadlock situation

Sorry, I should have mentioned that. In order to get backtrace you let the process freeze, attach gdb to it (it will freeze too), then go to /sys/fs/fuse/connections/ and find your fuse connection (it's most likely the one with non-zero value in "waiting" file). Then do "echo 1 > abort" and go back to gdb.
