Comment 1 Dr I JOrmshaw 2015-12-10 09:19:52 EST
This has been reproduced on 2 separate Fedora 23 systems and on Fedora 22, but not on Fedora 21.
Comment 2 Ngo Than 2016-01-26 06:18:37 EST
i can reproduce this issue. Is it the same kdevelop version on f21?
Comment 3 Dr I JOrmshaw 2016-01-26 07:34:49 EST
I've just booted up to a Fedora 21 live CD and installed kdevelop.  I get the same version as I have on Fedora 23
Comment 4 Ngo Than 2016-01-27 08:13:17 EST
please try new kdevelop-4.7.3 and give me feedbacks. This issue should be fixed in this new version

Comment 5 Dr I JOrmshaw 2016-01-27 10:22:44 EST
Where should I get that from as it doesn't appear to be in the update-testing repo?
Comment 6 Ngo Than 2016-01-29 03:56:35 EST
it should be available in update-testing. 

Comment 7 Dr I JOrmshaw 2016-01-29 05:17:41 EST
The fix has now appeared in update-testing.

From preliminary quick testing, I cannot reproduce the error.
