            Bug ID: 342679
           Summary: kded4 crash (not easily reproducable) launching
                    Firefox from Thunderbird
           Product: telepathy
           Version: 0.9.0
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: NOR
         Component: kded-module
          Assignee: kde-telepathy-bugs at kde.org
          Reporter: bucky at mightytikigod.com

While reading email and opening up a bugzilla link, DrKonqi popped up.

Clicking the email link again does not reproduce the error, so another trigger
must be at fault.

I searched for the "kded4" component DrKonqi listed at the top of the report,
but guessed wrong when I added my report to a bug I thought was similar.

I was asked to make a new report to (of all things) telepathy. So I'm picking
"ktp-kded-integration-module" because it has the word "kded" in it like DrKonqi
instructs at the top of the error report.

I was not chatting at the time. I was not receiving a chat at the time--that I
know of.

Reproducible: Couldn't Reproduce




I'm using up-to-date FC21 as of this date and time:
ktp-kded-integration-module-0.9.0-1.fc21.x86_64
qt-4.8.6-18.fc21.x86_64

The backtrace in the DrKonqi window looks like this:

Application: KDE Daemon (kded4), signal: Segmentation fault
