Created attachment 107139 [details] backtrace of KDevelop after SIGSEGV Imported a large project and while it was still parsing started to filter out directories I did not need and hit the same SIGSEGV twice in a row (see attached backtrace). On the third try I did not filter any directories and nothing went wrong. Steps: 1. Import large project 2. Exclude / filter directories from project. The GDB log does not include the SIGSEGV but it was on thread 1 at /usr/src/debug/kdevplatform-5.1.1/util/path.cpp:130.
