gitk won't start: unknown color name

[Ade Malsasa Akbar]

When I start gitk on Ubuntu 12.04 32 bit, I get this standard error on console:

Error in startup script: unknown color name "rgba:0000/0000/0000/dddd"
    (database entry for "-foreground" in widget ".___tk_set_palette.button")
    invoked from within
"$q .___tk_set_palette.$q"
    (procedure "tk_setPalette" line 82)
    invoked from within
"tk_setPalette background $c selectColor $selc"
    (procedure "setui" line 8)
    invoked from within
"setui $uicolor"
    (file "/usr/bin/gitk" line 11529)

I have no idea why this happen and how to resolve this problem.

This problem was solved a few minutes ago.

I followed this bug report on Red Hat Bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1043686. In there, I
should do "clearing out the X resources":

1) xrdb -load /dev/null (xrdb is X server resource database utility
from manpage)

2) xrdb -query

3) wish (wish is a Tk simple windowing shell application from manpage,
probably invoked for testing purpose only here)

4) I should uncheck KDE System Settings -> Application Appearance ->
Colors -> Options -> "Apply colors to non-KDE4 applications". Yes I
use KDE, and I have not mentioned it before. I am sorry. In KDE 4.10 of mine, I don't need to relogin.

Now gitk runs well again.
