i couldn't reproduce the bug. my box's specifications are, Qt: 4.7.1 KDE Development Platform: 4.5.4 (KDE 4.5.4) os:gentoo ~amd64 *** Bug 263359 has been marked as a duplicate of this bug. *** SVN commit 1214926 by aseigo: QString is not thread-safe; since the matches get shuttled around between threads, we need to protect access to it. as writing is rare, this should hopefully not degrade performance too much. if it passes testing, then i will backport this. CCBUG:238556 CCMAIL:plasma-devel@kde.org M +37 -0 querymatch.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1214926 *** Bug 281230 has been marked as a duplicate of this bug. *** Does this still happen? the latest duplicate mentions kde 4.6.5. is this fix supposed to be in that version, or only in kde 4.7? |
