(Forgot that I've already written a longer description about this bug, I put it down here:) (Note that all messages in double-quote are translated from zh-TW, and may be different to the actual source string) Recently I encountered a KDE software bug and a Kcrash window popped out, when I found the existing bug report and want to set my crash is related with it by clicking the "Suggest relationship with this bug" button in "bug description" window but nothing happened, thus interrupting the bug reporting process.
KCrash is the library, what you're talking about is DrKonqi. Reassigned.
