Does this problem also appear when running PK on the command-line? Please install the packagekit-dbg package and valgrind, then kill the running packagekitd daemon and run the following command in a terminal session:
sudo G_DEBUG=gc-friendly G_SLICE=always-malloc valgrind --tool=memcheck --leak-check=full --leak-resolution=high --xml=yes --xml-file=vgdump.xml --num-callers=20 /usr/lib/packagekit/packagekitd --verbose Then please send me the vgdump.xml file (attached to the bug) - you can send it in a private mail, if you want to. You may want to perform some tasks on PK via pkcon, like running `pkcon refresh` to give the daemon some work to do. Please quit the daemon by issueing the following DBus call: gdbus call --system \ --dest org.freedesktop.PackageKit \ --object-path /org/freedesktop/PackageKit \ --method org.freedesktop.PackageKit.SuggestDaemonQuit Cheers, Matthias
