[rkward-devel] Segfault loading package RWeka

[Egert, Bjoern]

Hello,

while loading the package "RWeka" I get the following segmentation 
fault:

> library("RWeka")

 *** caught segfault ***

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
