Thanks for the bug report! Could you describe what you did before the crash and which view mode (items/details/columns, previews enabled or not) you are using? Which Qt version exactly are you using (I suppose it's the RC of 4.5.0, as 4.5.0 isn't released yet)? I'm asking because the crash seems to be rather deep in Qt, so it might actually be a Qt bug. I don't remember, I have in default mode and view. *** Bug 185758 has been marked as a duplicate of this bug. *** *** This bug has been confirmed by popular vote. *** dolphin always crashes when preview enabled... Qt 4.5.1 raster engine KDE 4.2.2 ditto.

actually, this is slightly different. Preview is off, crash occurs when hovering over a text file, but not a pdf or image. I believe it's trying to preview in the information sidebar. This bug is caused mostly by using raster renderer in Qt. Please try it without that and i bet it wont be happening anymore. exactly, it deosn't crash anymore when raster is not activated. So, it is a bug, what can I do to have previews with raster activated ? just so you know, it also makes crash any application that shows a preview in the save/open dialog box.... Extremely annoying. (In reply to comment #9) > So, it is a bug, what can I do to have previews with raster activated ? Not much, probably. It looks like Qt's new raster renderer might still be buggy, so you should disable it until a more stable version is released (unless you want to track down the bug yourself). One more thing on the note. It is not happening with yesterdays 4.3 live dolphin. So you can assume 4.3 branch is clear and fixed for this issue. Probably close as fixed since no new stuff is going to happen in 4.2 branch? Can anyone else check Tomáš Chvátal discovery? Thanks No response and no more similar reports. Closing as WORKSFORME. Reopen if you experience this again on 4.3.0+/4.4 Thanks |
