Description raysoft 2012-04-27 12:49:13 UTC 
CPU utility is very high and it costs lots of RAM then kde become no-response when kwrite opens a file that contains only 3 bytes: EF BB BF.
However, there is no problem if I use gedit or vim to open this file.

Reproducible: Always

Steps to Reproduce:
1.create a new file
2.use any hex-editor to input these three bytes(in hex): EF BB BF
3.use kwrite to open this file
Actual Results:  
high CPU utility and it costs more and more memory and then kde becomes no-response

Expected Results:  
kwrite should open it very fast

My OS is Fedora 15 x86_64 and I use KDE 4.6.5

Computer will become no-response when kwrite opens this file because it costs too much RAM

Was fixed for KDE 4.7, please update. I will add your file as test case, though.
