Open Plan wih a file. 2. Edit a task; have the edit dialog open. 3. After some time, the program spontaneously crashes. Actual Results: The program crashed Expected Results: The program should not crash ;) 1312499 1 sombragris 2012-11-04 21:10:41 +0000 Forgot to specify version: 2.6 Beta1 1312958 2 dag.andersen 2012-11-06 07:58:49 +0000 Up front this looks like misconfigured system because this is common code to all calligra apps that has been around for a long time and it has been run countless times by anybody that makes a change to a calligra document. I cannot reporduce this on ubuntu 12.10. So are you certain that your system and AlienBobs packages fit together? (From the backtrace, it seems to be a mismatch between calligralibs and kdelibs) Could you check if other slackware users with same settup as you can test also? That said, it is always possible there is a bug somewhere in plan or other parts of calligra that triggers this, but I would be gratefull if you would check the two thing above first. 1313006 3 sombragris 2012-11-06 11:01:47 +0000 Hi Dag, thanks. As for your questions: 1. I'm certain that the packages are fine. 2. I don't know. I may be the only Slack user testing 2.6 Beta. However, you may have a point. Some months ago I was bitten by a bug that showed itself in okular. After a lot of crashes, hangouts, etc... we couldn't locate the source. Finally, it turned out it was a very subtle bug in Slackware's shipped version of gam-server. Right now, I see the bug only with 2.6 Beta, and not with the latest Slackware's 2.4.x shipped version. However, this might be exposing another subtle bug in the system. Who knows... I'll try to keep my eyes open. Thanks! 1313036 4 cbo 2012-11-06 12:29:33 +0000 kodocument::isModfied access parentPart and if that hasn't been set up for some reason it might crash - that said i find it weird that dag can't see the bug too if that is the case i've not tried myself 1347466 5 adaptee 2013-03-04 05:40:04 +0000 *** This bug has been marked as a duplicate of bug 310310 ***
