Description Leo Savernik 2006-01-15 20:53:13 UTC

Version:            (using KDE KDE 3.5.0)
Installed from:    Compiled From Sources
OS:                Linux

At least since KDE 3.5, KBabel crashes on this particular PO-file. KBabel for KDE 3.2 works flawlessly.

Backtrace (sorry, no debug info. I'll come up with some later):

po-file

KBabel 3.5.0 crashes reproduceably on this PO-file. The PO-file is valid as far
as it was generated by msgmerge, so it *must* be considered valid input for
kbabel (although it's "empty").

Comment 2 Nicolas Goutte 2006-02-05 22:42:35 UTC

Sorry, I cannot reproduce. For me, the file can be loaded.

Have a nice day!

Comment 3 Leo Savernik 2006-02-06 17:29:09 UTC

Whoops, I submitted the wrong file. One bug resolved by stupidity.

po-file -- this one crashes kbabel for real

But wait! Though the original offending po-file is lost, I managed to recreate
a similar one that exhibits the same bug.

This time I double-checked it's the right file.

Comment 5 Nicolas Goutte 2006-02-06 17:52:33 UTC

Superb! The whole file is "outdated"!

If you want to fix such a file, use msgattrib:

msgattrib -o out.po --clear-obsolete in.po

Otherwise I suppose that part of the problem is the same as in bug #117968 or even bug #121236 (as here too there is no header).

Have a nice day!

Comment 6 Nicolas Goutte 2006-02-11 11:44:53 UTC

Attachment 14577 [details] loads now with an error. 

(As KBabel does not actively handle obsolete entries (but only keeps them as comment of the end of the document), there is nothing else that can be done.)

Have a nice day!
