Description Luke-Jr 2004-02-09 19:27:06 UTC 
Version:            (using KDE KDE 3.2.0)
Installed from:    Gentoo Packages

When the Load/Save dialog opens (tested from KWrite and Kate, though probably in other apps too), the application reads a bunch of files (appears to be from the recent file list).
I don't see any purpose for this from the UI (the data isn't actually used as far as I can see), but the actual problem is when it tries to open network files (where access to the file attempts to connect and, if the remote host is down, will block until it times out).
Either the file access should be removed or something should be done to prevent the blocking from freezing the entire app.
From strace while the app is frozen:
	stat64("/mnt/net/smb/kazumichan/home/Main_Memory/benedictine/classes/done.txt",
/mnt/net/smb/A/B makes a samba network connection to \\A\B and will usually block until it times out or succeeds.
Comment 1 Raúl 2006-12-14 18:38:22 UTC 
I think I have suffered same problem. I have two dirs mounted on a NFS server. When this server was turned off, the system started to become unstable. One instance of Konqueror froze (with a lot of opened tabs :/ ). This instance was using those shared dirs among others.

After killing this freezy instance while trying on no success to get a backtrace with gdb, I tried to open the file selector dialog with cervisia. This also froze cervisia, but this time I got a backtrace:

Then I force umounting the NFS shares and everything went normally.

There shold be some way to avoid this major freezing behaviour or at least having a warning dialog about this issue. Common users should notice this is because of an dissapearing NFS share.
Comment 2 Raúl 2006-12-14 18:38:56 UTC 
I forgot to mention I use debian testing with kde 3.5.5.
Comment 3 lexual 2010-01-23 05:38:37 UTC 
Still relevant to recent KDE version?
If not please close the bug.

Thanks,

Lex.
Comment 4 Raúl 2010-08-25 23:50:11 UTC 
Hello:

I've did some tests with 4.4.5. So far I just got to browse with NFS, not that I had much success on the attempt, but at least konqueror did not froze.

I'll try soonish also with the save dialog.

Regards,
Comment 5 Christoph Feck 2011-07-25 19:02:35 UTC 
If you can provide the information requested in comment #3, please add it. The important information (whether it still happens with file dialogs) is missing from comment #4.
Comment 6 Raúl 2012-06-14 07:28:55 UTC 
Hello:

I've just tested this and I think it's solved. KDE 4.7.4 on Debian testing.
