Hi Per,
I had a look at your trap file, and near the bottom in the 'DLL's accessable from this process' section the tale is told: you have 2 versions of libcn0.dll loaded, one in G:\usr\lib (the correct one) and one in P:\OPENOFFICE\PROGRAM (an older one). Not sure how the 2nd one got there, but I notice there are several other duplicates in those same 2 directories (like libcx0.dll, pthr01.dll, icudt.dll, gcc1.dll) some of which are the same version, but not all. Best to get rid of the ones in P:\OPENOFFICE|PROGRAM (I do not have any of those there on my system). Might be easiest to delete P:\OPENOFFOCE and re-install OpenOffice from scratch.
I also notice that none of the OpenOffice DLL's are loaded high - once OpenOffice is installed, go to the 'Apache OpenOffice' folder, then the 'Extras' folder, then run 'Enable High Mem Code Loading' and reboot to get OpenOffice out of your low memory.
HTH,
