i assume you can't boil it down into a simpler test case than using GConf? 

if not, i suggest:
-use a recent tcpdump and watch the network to see exactly what
operations are sent (tcpdump -vv -s 1500 port 7000 and host yourhost 
 should be sufficient)
-make sure fstrace is configured usefully (afszcm.cat installed in
 /usr/vice/etc/C or wherever you've compiled afs to expect it)
-enable fstrace on the client (fstrace setset cm -active) , make the
 problem happen, fstrace dump cm > somefile
-send the packet trace and the fstrace dump to openafs-bugs@openafs.org
