Comment 1 Kevin Funk 2016-02-03 10:36:12 UTC 
Does reverting 794fa0f from kdevplatform.git help?

If yes: Please tell me which project you're trying to open.
Comment 2 Kevin Funk 2016-02-03 10:38:16 UTC 
Hm. I see there's kdev-php involved, too:
#16 0x00007f4744dcbe67 in KDevelop::DUChainItemFactory<Php::PhpDUContext<KDevelop::TopDUContext>, KDevelop::TopDUContextData>::dynamicSize (this=0x513b0a0, data=...) at /opt/kde5/include/kdevplatform/language/duchain/duchainregister.h:80

Can you make sure your kdev-php build is not out of date?
Comment 3 Kevin Funk 2016-02-05 09:38:18 UTC 
@Aleix: Can you check? This is rather important to us. Issues in KDevelop::TemporaryDataManager would be super severe.
