this crashes when assigning a qstring... what on earth could go wrong with that? Qt bug? [Comment from a bug triager] Bug 259187 talks about the similar situation and it also hits "Plasma::AbstractIcon::setSelected"; may be there is something in common ? *** Bug 259187 has been marked as a duplicate of this bug. *** Confirmed by duplicate, but that was 4.6 beta, is this still valid with KDE 4.8.3? I'm still on KDE 4.8.2, but it seems I can remove activities now just fine. Also adding & removing various activity-related widgets and they all work fine. Thank you for the feedback. |
