Bug 305570

Everything appears to be working fine with spell checking in the KMail2 composer window with the exception of the visual part of highlighting misspelled words with automatic spell checking enabled. If you right click on a deliberately misspelled word, it offers suggestions, so the actual checking part seems to be working - there's just no underlining of the word.

I searched for some appearance option within KMail or in System Settings but could find nothing relevant, except for an item for "Misspelled words" within the custom colour settings, but neither enabling and disabling custom colours nor changing the colour had any effect. As a test I enabled automatic spell checking in KWrite and it does underline misspelled words there, as does Calligra Words, if either of those makes any difference.

Reproducible: Always

Steps to Reproduce:
1. Open the composer window
2. Type an obviously wrongly spelled word (e.g. wrod)
3. Press enter
4. Right click on the word
Actual Results:  
3. Word is not underlined in red
4. Menu containing spelling suggestions pops up

Expected Results:  
3. Word is underlined in red
4. (This part works as expected - just proves spelling engine is working)
