Error: cond.formatting with pivottable

[Chartman of the Bored]

I'm using conditional formatting on a column that contains a pivot table. The formatting formulas work fine, but Excel crashes when I try to print the worksheet. When I remove the cond. formatting, the thing prints without any problems. Have you come across this problem ever?

I "solved" it by de-activating the pivot table (copied it and then did a paste-special-values over it). But I'm wondering if this is a known issue...
