Bug#479742: kbabel: Very long window refreshing on long files
Package: kbabel
Version: 4:3.5.9-1
Severity: normal
When changing virtual desktops in KDE and going back to KBabel's one it
takes reasonable amount of time (a few seconds, e.g 10s) to redraw
KBabel window, during which KBabel is just frozen.
Steps to reproduce:
1. Run KBabel
2. Open a .po file
3. Switch desktop to different one
4. Go back to KBabel's desktop
Now the situation happens.
What can be related to this bug:
1. Size of .po file - the bigger, the longer time is. Not verified,
though.
2. KBabel's database - I can remember that some crashes in KBabel were
fixed after a database directory removal. I can't remember what it was
exactly.
After attaching strace to KBabel it reveals that:

14:12:47 ioctl(16, FIONREAD, [64]) = 0 <0.000011>
14:12:47 read(16,

<0.000054>
[cut]
so there are no system calls during that time.
