Comment 1 Christoph Feck 2014-07-15 15:47:47 UTC

Crash is in the KLatexFormula plugin. Can you confirm that disabling that plugin resolves the issue?

Well it seems that disabling KLatexFormula did the trick. Kile doesn't crash anymore. Thanks for help.

Comment 3 Christoph Feck 2014-07-20 00:58:32 UTC

Can you try updating to KLatexFormula 3.2.10? It should fix this crash.

With klatexformula 3.2.10 kile works fine.
