Comment 22 for bug 1053910

Simulating the same command like as it was executed by Chrome (it's doing the same):
$ time kdialog --attach=56623340 --title="Open File" --getopenfilename /home/kenorb/Downloads/
kdialog(8234)/kdecore (K*TimeZone*): KSystemTimeZones: ktimezoned initialize() D-Bus call failed: "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

real 1m42.668s
user 0m0.496s
sys 0m0.088s
Time when kdialog was run and first attempt to click Cancel.

dbus-daemon is run for current user:
