Steps to reproduce the issue: 0. Start kdevelop 1. Create or open a kdevelop C/C++ project 2. Open a C/C++ file in the editor 3. Close kdevelop 4. Run "strace -f -o kdevelop.strace kdevelop", open the project if required 5. Close kdevelop 6. Run "grep utimes kdevelop.strace" $ grep utimes kdevelop.strace 21302 utimes("file.cc", [{tv_sec=1486969933, tv_usec=0}, {tv_sec=1486969933, tv_usec=0}] <unfinished ...> 21302 <... utimes resumed> ) = 0 See also: man utimes, man strace Related bugs: #226117

I suggest to completely delete class FileModificationTimeWrapper.
Thanks for the report, but I think bug 226117 contains all necessary information already. Thanks for the strace & gdb output. Marking as duplicate. *** This bug has been marked as a duplicate of bug 226117 ***

Please raise the importance of bug 226117 in its header to increase the probability of getting it fixed for kdevelop 5.1.0. Thanks.
Done. Unfortunately that won't really affect the probability this is getting fixed. Stepping up & contributing a patch would increase probability a lot more ;) See: https://www.kdevelop.org/contribute-kdevelop

It seems to be a much better tool than previous KDE developer workflow management tools.

From internet search, it seems to be an abandoned thing from year 2003. It may be beneficial to completely remove unsermake support from kdevelop.
KDevelop still references unsermake? Patches removing that are very welcome.
