Dear LyX developers, trying the example from http://www.lyx.org/trac/ticket/10456 with LyX 2.3.0dev (2016-10-28) Git commit hash 42d900c2 CMake Build
I was met by a crash. How to reproduce: * Turn on the source pane (current paragraph, automatic update) * Change the language of the albanian part to afrikaans. With the change: * Open the file, * Move the cursor into the paragraph with afrikaans. Crash! No problem, if the code preview is closed.

Please read the bug-reporting instructions in 'Help->Introduction' and send us a bug report, if necessary. Thanks! Bye.
