If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? Thanks :)

hi
sorry for the delay in responding. my internet connection had been down.

i could reproduce the situation a couple of times. i couldnt get a screenshot
/ record video of that activity though. am confident of the steps involved in
stimulating the bug.

1. open kmail and open a mail with some hyperlink (as shown in the screen
shot).

2.      right click on the link and choose copy link location from the kmail's
context menu.

3.      klipper's action menu popups up.

4.      Choose open with default browser (I have edited it to make opera as my
default browser). (snapshot2)

5.      opera gets launched.

6.      Action menu popup still visible.

7.      Click on the same option once again.

8.      klipper crashes.

Thats about it.

The reporter sent me another email:
------------

further to my response sent a while ago about the bug,

I checked it out further and i guess the crash is due to the second click on
the action pop up of klipper after the first one ALREADY launches the
associated process.

am attaching the screen shot of the klipper crash for ur kind information.

Can you take a look at http://fedoraproject.org/wiki/StackTraces to know howto generate a full backtrace (you will need to install kdebase-debuginfo), and then post the bactrace (the details in the KCrash dialog) here?

Thanks

=================

and as is obvious, kmail has got nothing to do with this. when any url copied
to clipboard, the klipper action menu pops up. choosing an action works
normally as expected. ideally the action popup should go off at this juncture.
but it doesnt. it persists. when the action is chosen again, klipper crashes.

hope this information helps.
regards

Thanks a lot :)
