As bug 198163 and bug 176014 (from Konqueror and Plasma), this is supposed to be a bug in the Qt raster paintengine. Hmm well i hate it *g seeing at least one of the other bugs' reporter uses QT4.5.1, downgrading wouldn't be of much help huh.. i reckon the trolls are aware of the issue and on it? Do you know if your Qt is compiled to use the raster paint engines as the default graphics system ? Thanks I analysed the multiple backtraces about those Qt "blend" bugs. 1. Qt uses the raster paintengine as a fallback, even if the user does not have configured it as the default paintengine or used the command line argument to select it. 2. The floating point exception and the 0 address seg fault is due to a bug in Qt missing a check about invalid images. I hope to get the fix into Qt before 4.5.3 is hitting RTM :) I merged all the similar reports into bug 176014 and added the description of comment 4. Merging this report too. Thanks *** This bug has been marked as a duplicate of bug 176014 *** |
