#52 YAGF crashes when spell checking is on

[Anonymous]

Originally created by: kov...@gmail.com

What steps will reproduce the problem?
I did following.
1. Opened first PDF page in YAGF.
2. Chose English-Russian language to recognize.
3. Pushed 'Select Text Area' button.
4. Pushed 'Recognize'.
Also 'Check Spelling' button is pushed by default.

After some time YAGF crashed. It happens every time. If to do all that steps with unpushed 'Check Spelling' button all is OK - no crashing.

What version of the product are you using? On what operating system?
YAGF 0.9.4.3
Kubuntu 14.04 LTS
Linux x86_64 3.17RC6
Aspell 0.60.7~20110707-1ubuntu1

Here is YAGF backtrace:
