[TYPO3] extension line breaks disappear

[Katja Lampela]

Another question about simplecalendar; the event description's line 
breaks don't show in FE even though they do in BE. All the other rte 
texts show line breaks fine.

I have the following lines in ts setup, but they wont't help.

plugin.tx_desimplecalendar_pi1.eventDetail.marks.description.20.parseFunc 
= < lib.parseFunc_RTE

plugin.tx_desimplecalendar_pi1.general_stdWrap.parseFunc.nonTypoTagStdWrap.encapsLines.addAttributes 
{
P.style =
PRE.style=;
}

Anyone knows what might do the trick?
