Switching “Show post count” on creates a new line between name an count

Hello,

i would like to show the post count for each of the categories in my category-list.
I use the default widget for displaying the list.

At the moment the post count is deactivated, so please have a look at how the category-list does look right now: https://blog.matrixagents.org/

When i switch the option to show post count on, unfortunatelly it creates a new line between name and count, see here: https://matrixagents.org/screencasts/2008-08-18_1539.png

I would like the post count only to be separated from the name by a “space”, nothing more.

I already tried searching through the theme’s files, but couldn’t find anything that would make sense to me. Also tried looking for the widget’s code, but although i know PHP, WordPress’ code can be a real pain in the ass, i think.

I would be very glad, if anybody could tell me, _where_ i have to change or at least start to look at, in order to change that.
If you need to see any code, please just tell me what and i’ll post it.

Thanks in advance!
