Hi guys,

I posted the below to kde-devel at kde.org<mailto:kde-devel at kde.org> before I was a member of the list so I'm not sure whether it got through or not.
Hence, I thought I re-post now I am a member - I would appreciate any advice.

Thanks very much in anticipation,

Subject: Kleopatra Locking Clipboard

Hi there,

Application: Kleopatra (Certificate Manager and Unified Crypto GUI)
Version: 2.1.0
KDE Version: 4.1.4

I am a developer who is working on a piece of software that accesses the Clipboard.
I am experiencing a problem whereby when trying to access the Clipboard an ExternalException is thrown with the following error message: 'The requested clipboard operation did not succeed'. As a result, I did some diagnostic work to try to work out which application was locking the Clipboard. There seem to be a number of different applications that sometimes lock it (presumably whilst they have access to it).

However, the worst offender seems to be Kleopatra.exe. By 'worst' I mean it seems to persistently lock the Clipboard and thus blocks our application from accessing it. We are not actively using Kleopatra when this problem occurs; it is just running in the background. Also, interestingly this problem does not always seem to happen; sometimes Kleopatra doesn't seem to access/lock the Clipboard.

I was wondering if you might know why this is and if there is anything we can do to prevent Kleopatra.exe from persistently accessing the Clipboard?
