When going through the styles popup, in this case looking for certain fonts, I repeatedly picked a new style without closing the modify dialog box. This appeared to create a stack of dialogs ( there was a strange heavy shadow, but no cascading view) and eventually ( maybe 25 styles) locked up my system, forcing a hard reboot.
I am unable to reproduce this with LO-3.4.5-rc2-x86_64 on SLED11-SP1. I do not see any extensive CPU or memory usage. I know that it is a bit painful because it reboots the system. Though, are you able to reproduce this? It is possible that the problem is not caused by the many dialogs but with a particular style or font. If you are able to reproduce this, please, try to remember what style or font you selected just before the crash. BTW: LO-3.3 is pretty old. We do not longer provide bug fix releases for this code base. You might consider to switch to LO-3.4.4. Note that LO-3.4.5 is going to be available the following week. Hmm, this looks like a corner case. It is hard to reproduce and not so common scenario => can't block the release => lovering the severity a bit.
Understand your changes. 3.3.4 is the latest for Ubuntu Natty, which is only one release behind. Will try to reproduce on another machine. This original one is too busy to crash again :) one clarification: I was looking for styles, and clicking "modify" on styles, without canceling the previous dialog box ( I couldn't see it ). The font I was looking for was Courier10pitch, but mostly I wasn't finding it, so the font was Arial, Times New Roman, or CourierNew - the standard MS fonts.
Dear bug submitter! Due to the fact, that there are a lot of NEEDINFO bugs with no answer within the last six months, we close all of these bugs. To keep this message short, more infos are available @ https://wiki.documentfoundation.org/QA/NeedinfoClosure#Statement Thanks for understanding and hopefully updating your bug, so that everything is prepared for developers to fix your problem.
