Comment 15 Valentin Rusu 2011-02-01 00:33:24 UTC

I found the origin of the problem and commited the one-line fix on git.kde.org.
But I cannot close this bug. Someone in this list can do that ?

Comment 16 Raphael Kubo da Costa 2011-02-01 02:31:06 UTC

Can you backport your fixes and indicate which commits fix the issue? I can close the report after that.

BTW, please file a sysadmin bug report or contact the Bugsquad team to get enough karma to close bug reports.

Comment 17 Frank Reininghaus 2011-02-01 16:06:21 UTC

Valentin, nice fix! Backporting makes certainly sense, as Raphael said. Moreover, it would be great if you could write a unit test and add it to konqueror/src/tests/konqviewmgrtest.cpp, just to make sure that the bug never comes back again.

Just for the record, the commit in master is

https://projects.kde.org/projects/kde/kdebase/kde-baseapps/repository/revisions/f3e5f29a0f601b3d2825be73c25ff9406f409b6d

Well, I never done that before.
I suppose that :
- I need to go back to SVN to get the branches,
- apply the fix and commit (I obviously have a SVN account).

One question : how many release back should I go ?

Valentin

Comment 19 Frank Reininghaus 2011-02-01 21:17:31 UTC

Only backport to the KDE/4.6 branch, which is in the kde-baseapps git repository.

Comment 20 Valentin Rusu 2011-02-01 21:42:27 UTC

Fix backported to origin/KDE/4.6 as of 
http://commits.kde.org/kde-baseapps/69526109af7fd4d058442fcf4d00d7e6e73a5c2a

Now trying to write a unit test for the origin branch.

Comment 21 Frank Reininghaus 2011-02-01 21:50:18 UTC

Great, thanks Valentin!
