segmentation fault in Linux (Fedora 25)

[ousia]

@Bramas,

I’m afraid I get segmentation fault when I search (Ctrl+f) when TeXItEasy has no file (no tab in the editor).

Here is what I get (with backtrace):

Starting program: /usr/bin/texiteasy

Just in case you might fix it. (I can promise this is all Greek to me 😉).
