Sorry, you can disregard this. I can reproduce. The previous comment was based 
on a GnuCash version before the gtk+ updates.

By default unselected tabs are black. This seems to be related to the account 
tab coloring (ie the addition of an event box in the tab): the preferences 
tabs are not influenced. Also if you set a color for one account, that 
account's tab will be displayed properly with the chosen background color.

But as said before, other themes don't seem to be affected. So we should 
perhaps indeed select another theme. The default theme is set via dist-
impl.sh, line 114. It can be easily changed. Any suggestions to a good 
replacement theme ?
