Backtrace stopped: frame did not save the PC

This is on the kde distributed packages of kde 3.5.7 for Ubuntu feisty on a 32bit system.

Comment 1 Sergio Callegari 2007-06-25 13:32:16 UTC

In fact a 3.5.7 regression.

Downgrading to the official Ubuntu feisty package (namely 3.5.6-0ubuntu20.1) fixes the issue.

Comment 2 Guillermo Antonio Amaral Bastidas 2007-06-26 08:33:39 UTC

I fixed this is fixed in SVN branch 3.5 a few weeks ago

Comment 3 Dominik Haumann 2007-06-26 10:36:17 UTC

jo, fixed ;)

Comment 4 Sergio Callegari 2007-06-26 13:17:10 UTC

Will it be possible to get updated binaries?
I am particularly interested in Ubuntu feisty, but maybe the binaries for other distros share this issue too.

Comment 5 Guillermo Antonio Amaral Bastidas 2007-06-26 18:21:45 UTC

 I am not sure how Ubuntu handles it's repository but you might need to contact the package maintainer so he can apply the required patch.

Comment 6 Sergio Callegari 2007-06-28 13:05:29 UTC

I sent a report on the ubuntu bug tracking system, pointing the maintainer to your patch.  The patch was incorporated on the distribution SCM:

> Committed to bzr. Will upload to gutsy after the freeze is over, and after i've > fixed some more of the bugs.

Unfortunately, there is no mention about an updated package for feisty and this is a pity, since kubuntu will continue advertising a kde 3.5.7 repo with a broken kate.

To the rescue, note that you can mix the packages from the kde 3.5.7 repo with kate from the 3.5.6 repo. After you do so, apparently you get a working kate from the 3.5.6 repo happily report that it is kate 2.5.7 on kde 3.5.7.
