Not especially. Having symbols would help. It's going to be something in 
foreach() in lib/cyrusdb_quotalegacy.c, though, since that's the only 
place you'd be using the system glob().

I suppose, for simplicity, you can just add a

printf("%s\n", quota_path);

before and after
     /* strip off the qr specific path and replace with pattern */
     sprintf(strstr(quota_path, FNAME_QUOTADIR) + strlen(FNAME_QUOTADIR),
             "?/%s*", prefix);

And see what 2 lines you get just before the crash, as a way of cheating.
