Can't reproduce. If it freezes, could you attach gdb to the process and
send me the backtrace?

Sorry I don't know much about gdb so I would like to ask you to tell me what
exactly I need to do.

No problem:

1. Make catalog manager freeze
2. in xterm/konsole do "ps ax"
3. there is a line like "17726 pts/4    D      0:01 catalogmanager"
The first number is the process PID
4. do "gdb -p <catalog manager pid>"
5. after a while, you get a prompt: (gdb)
6. type "bt" and you should get a list similar to the one from the KDE Krash dialog
7. send me the result of the bt.

Sorry for being so late with this. I had some other work to do.
This is what I get:

(gdb) bt
#0  0x408038d1 in posix_memalign () from /usr/lib/libkdecore.so.4
#1  0x00000014 in ?? ()

This is what I get if I try to move a file into the watched folder (the previous
output was to move it out):

(gdb) bt
#0  0x40dcdf41 in QString::setAscii(char const*, int) ()
   from /usr/lib/qt3/lib/libqt-mt.so.3
#1  0x40dc679b in QString::operator=(char const*) ()

#3  0x40b24c58 in QObject::activate_signal(QConnectionList*, QUObject*) ()
   from /usr/lib/qt3/lib/libqt-mt.so.3

I tried once agin to move the file out of watched dir and now I also get this:

(gdb) bt
#0  0x40dc677d in QString::operator=(char const*) ()
   from /usr/lib/qt3/lib/libqt-mt.so.3

#3  0x40b24c58 in QObject::activate_signal(QConnectionList*, QUObject*) ()
   from /usr/lib/qt3/lib/libqt-mt.so.3

It seems like a miscompiled code to me. Which mandrake and which RPMs?

I use Mandrake 9.2 RC2 with kdebase 3.1.3-78mdk, kdelibs-common 3.1.3-35mdk
libqt3 3.1.2-14mdk and kdesdk 3.1.3-9mdk.

I now also tried on a completely different computer which has Gentoo Linux
installed. I also get a freeze here. I will post gdb output after I emerge it here.

I now also tried with KDE 3.2 Beta 1 and the problem is still here :(

*** Bug 78864 has been marked as a duplicate of this bug. ***

So it still exists.

And it is istill here in KDE 3.3.0 Beta 1. What I noticed now is that it only freezes when adding/removing *.pot file into a watched POT folder while Catalog Manager is runing. It seems to be fine when doing the same with *.po files. This is on a completely new computer with Gentoo Linux and I compiled with GCC 3.4.0 for AMD64.

OK. I'll try to reproduce via removing POT file.

No luck :( Does catalog print any debug information?
Try to run it from the console and look for messages.

Also, does it start to be responsive again after some time?

OK I now started catalogmanager from command line and moved kopete.pot out of watched folder. And no It never becomes responsive again. Here is what the whole console output is from the begining to freezing:

This is very strange:
catalogmanager: directory changed: T/kdenetwork/ 
 
Could you, please, send me your kbabel.defaultproject?

Created attachment 6878 [details]
kbabel.defaultproject

Here is my kbabel.defaultproject file.

It seems the problem is with the names of the folders. Try other than
PO/POT.

But I can reproduce is now.

You are right. I just renamed PO > pos and POT > pots and now it doesn't freeze anymore. Thanks!
It would still be nice to get the freezing with original folder names fixed.

That's why I didn't close the bug ;)

Is this going to be fixed for KDE 3.4. Just a reminder :)

Don't know :(

I still can't reproduce the problem :(

In comment #20 you said:
It seems the problem is with the names of the folders. Try other than 
PO/POT. 
 
But I can reproduce is now.

Sorry for confusion. I'll take a look.

CVS commit by nanulo: 

Try harder to find out if PO or POT directory is changed/deleted
