This crash is evidently triggered when an attempt is made to render Burmese results, and there seems to be difficulty rendering certain combining characters from the Burmese codepage. For example, လးျဖဴ

*Note* The branch linked for unity will just be a workaround. The overall problem is in pango/harfbuzz. I need to make a small example to demo the problem.

Also crash with "wri" and "syn" when LibreOffice Writer is running on my Saucy 13.10 x86-64/nvidia.

It seems that key words of 3 letters cause crashing. "writer" cause no crash, for example, but "wri" crash.

But don't crash when "unity-lens-friends", "unity-lens-photos" and "unity-lens-viodeo" are removed.

Luc: I can confirm the crash with 'wri' on Saucy, but not on Trusty.
The backtrace on saucy looks similar to me to this bug.

That seems resonable. "wri" Must be pulling in some suggestions from one of those lenses that is causing the crash. It was happening more in trusty, as it pulls from more lenses. Ill look into backporting the workaround asap!
