Follow-up Comment #4:

Reopened since bug is confirmed on Kubuntu 12.10 and 13.04. Detailed
information from Thorsten Liebig's post in the maintainers mailing list:

I have a strange problem with the Octave GUI on Kubuntu 13.04 and it already
existed on Kubuntu 12.10

If I want to open or save a file, the file dialog and Octave freezes. At the
same time I get this message in the Octave terminal: "KGlobal::locale():
Warning your global KLocale is being recreated with a valid main component
instead of a fake component, this usually means you tried to call i18n related
functions before your main component was created. You should not do that since
it most likely will not work"
But this seems not necessarily related to the freeze (see below)

If I wait a couple of minutes, I get on the Octave terminal:
QProcess: Destroyed while process is still running.
QProcess: Destroyed while process is still running.

After this two messages, I can browse the files normally and open/save.

But this two processes that got killed seem to be important, because after
this Octave behaves strange...
E.g.: Sometimes the entire GUI freezes or at least doesn't get updated if a
script is running...
If I'm patient again, I get again:
"QProcess: Destroyed while process is still running."
And the GUI unfreezes again...

I tried a fresh Kubuntu 13.04 on a virtual machine and did *not* see this
problems, except the "KGlobal::locale()..." message, but no freezes...

- Switch to language en_US does not help.
- No other dialog cases any problems
- Octave does not crash or segfault, I just can't do anything else than wait
for the two QProcess to be destroyed. After that I can more or less work
normally, even the file-dialog works fine after that...
