Hi all.
I can replicate the mysterious R-plugin crash: it happens systematically
when I enable on the fly CRS transformation with several rasters and
vectors in different projections.
QGIS self compiled from svn, fresh.

Here is the message:

Critical: QgsCoordinateReferenceSystem::createFromWkt -- theWkt is
uninitialised, operation failed
Critical: QgsCoordinateReferenceSystem::createFromWkt -- theWkt is
uninitialised, operation failed
Warning: QPainter::end: Painter not active, aborted
Warning: QPainter::begin: Cannot paint on a null pixmap
Warning: QPainter::setFont: Painter not active

Warning: QPixmap::scaled: Pixmap is a null pixmap

 *** caught segfault ***
address 0x7fc3bcdf4000, cause 'memory not mapped'

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: Exception in thread Thread-1:

All the best.
