Comment 1 Sven Brauch 2013-05-03 16:30:32 UTC 
I can't reproduce it, at least the repository parses fine in 1.5 (didn't try the 1.4 -> 1.5 step since I think it's unrelated).

Anyways, to me this looks like a broken setup. Can you please verify that $KDEDIRS/share/apps/kdevpythonsupport/documentation_files/ exists and is readable ($KDEDIRS is /usr on my distros)?
Comment 2 Sven Brauch 2013-05-03 16:34:21 UTC 
Ah, if that's not it, then please try deleting ~/.kdevduchain and ~/.cache/kdevduchain.

Comment 4 Sven Brauch 2013-05-03 16:50:18 UTC 
The data dir must contain a documentation_files directory. It contains the python API, which is read by the parser and is vital to the correct functioning of the plugin. The plugin shouldn't crash but display an error message instead (I'll fix that) but the problem is that it's not installed correctly. If this is from your distribution's package, please report a bug with them about it.

Closing as invalid.

Cheers,
Sven
Comment 5 Dmitriy A. Perlow 2013-05-03 16:51:51 UTC 
Thanks a lot!
Comment 6 Sven Brauch 2013-05-03 16:54:46 UTC 
As a workaround, you can try
git clone git://anongit.kde.org/kdev-python
sudo cp -R kdev-python/documentation_files/ /usr/share/kde4/apps/kdevpythonsupport/
Comment 7 Dmitriy A. Perlow 2013-05-03 16:56:38 UTC 
There is doc-subpackage at openSUSE, but it isn't required y the main one. Thanks!
Comment 8 Sven Brauch 2013-05-03 17:05:48 UTC 
Did you check, and does installing the doc package work? That's good ;)
Should I tell the SuSE people, or did you create a report already?
I should probably pick a less confusing name for the directory to make sure people don't get it wrong again.
Comment 9 Dmitriy A. Perlow 2013-05-03 17:07:12 UTC 
Yes, I did.
No, I'll do it.
Comment 10 Sven Brauch 2013-05-03 17:38:07 UTC 
Would you mind posting the link to the report here, for future reference? Thanks.
Comment 11 Dmitriy A. Perlow 2013-05-03 18:00:53 UTC 
I've already posted: https://build.opensuse.org/request/diff/174462

Additionally, you could add a README.packagers (or whatever name) with this notice
Comment 13 Sven Brauch 2013-05-03 18:23:54 UTC 
Yes, that's what I was planning to do. Thanks for the link (and for the report in the first place).
Comment 14 Dmitriy A. Perlow 2013-05-03 18:31:52 UTC 
It's a pleasure! Great thanks for immediate reply!
