This is from an openSUSE 11.4 (i586) installation when accessing certain
directories on a NetWare 5.0 server which is mounted via NCP.
It happens with *all* openSUSE 11.4 installations, but it never happens with an
older SuSE/openSUSE version. We have some machines here running e.g. 9.3 / 10.3
/ 11.3, and no problems accessing the same NetWare server.
In the case above this happened when I used Dolphin to browse the NetWare
server, but it also happens when some other application opens a open file or
save file dialog box and you browsw certain directories, or if you enter "cd "
in a console window and then press the tab key for autocompletion, in which
case the directory is scanned.
First I assumed this was due to a directory entry with special characters (e.g.
umlauts), but this does not seem to be the case.
Actually I'm not sure if the reason is a large number of directory entries, or
simply a large workload when browsing a directory.
This is really ugly. I can provide additional information, if required. Just
let me know.
