#2950: Tahoe backup crashes while collecting file list

-------------------------------+---------------------------
 Since upgrading to 1.13.0, there is something in some of my filesystems
 that causes the tahoe backup command to crash.  I've not been able to
 isolate exactly what yet, but some sets of files are fine and some crash
 before it even starts uploading.

 After some experimentation I've discovered that device nodes are one of
 the things that will trigger the crash.  But one of the backup sets on
 which it crashes doesn't appear to have any, so either I haven't found the
 hidden one yet, or there is some other special file type that trips it up
 as well.

 Unfortunately the stack trace doesn't offer me any intelligible hints
 about what file is causing the problem, but I'll include it anyway in the
 hope that it will make fixing it a little easier.
