Hello! You have something valuable on your hands, a way to reproduce the problem that will dump you into a debugger (usually) close to the location where the bug is happening. If you could take a backtrace of the crash, that could get us to a solution more quickly. It seems like an important bug. (formal stuff) While the kind of your message is suitable for top-posting on its own, I suggest that you still keep bottom-posting on a technical mailing list such as this. At some point, it's going to get into technical details again and then it's good to have everything in chronological / topical order top to bottom. > On 21 June 2015 at 20:29, Andreas Hartmetz <ahartm...@gmail.com> wrote: > > On Sunday 14 June 2015 15:00:57 Milian Wolff wrote: > >> Hey all, > >> > >> in massif-visualizer's framework branch, and now also kate, I > >> sometimes notice GUI lockups when I try to open files via Ctrl + O. > >> The backtraces look like the following: > >> > >> https://paste.kde.org/pbzhkgx8r > >> > >> Any idea what might be going on here?
