This is a grave bug, please revert that commit or fix it before it's to late (4.5.2 tagging) - also it would be very nice to keep 4.5 branch actually stable and safe from unsafe (probably untested or overlooked) backports. Thanks in advance! I cannot reproduce this one. Could you please attach the backtrace since the line numbers are cut here. *** This bug has been marked as a duplicate of bug 249269 *** |
Version: unspecified (using KDE 4.5.0) OS: Linux Commit 1168845 in 4.5 branch "Backport: 2 bug fixes in Entiry management: do not crash when comparing empty entities and fix ref counting." introduces crashes in libnepomuk. Reverting to previous revision (1168450) fixes the problem. Reproducible: Always Steps to Reproduce: 1. Update kdelibs to 1168845 and rebuild 2. Start anything Nepomuk related (for instance dolphin --nofork with Nepomuk enabled) Actual Results: Anything using Nepomuk crashes almost instantly (dolphin, nepomukservicestub) Core was generated by `dolphin --nofork'.
