Comment 18 for bug 32915

I think I found the problem, at least at my pc. I am using Hungarian localization on the machine, and so the numbers are written in eg. 2,5 form instead of 2.5 by default.
So, when the gamma values are given in a list in this form (line 431):
self.availabletargetgammas = [unicode(i18n('1.4')),unicode(i18n('1.6')),unicode(i18n('1.8')),unicode(i18n('2.0')),unicode(i18n('2.2')),unicode(i18n('2.4'))]

all the dots are changed to commas because of the localization procedure. In line 1028, however the program searches for a simple string, without localization:
t = self.config.readEntry("targetgamma","2.0")
and later in line 1034:
t = '2.0'

The problem can be solved either by removing i18n from line 431 or by adding it also to lines 1028 and 1034 to get:
t = self.config.readEntry("targetgamma",unicode(i18n("2.0")))
and
t = unicode(i18n('2.0'))
respectively.
