I've hacked up the smsImporter today, I've tested it on nemo since I don't have a device, so no guarantee for it's functionality.

Running the binary with the exported csv as argument imports everything
Binary: http://cdnm.at/~christian/Harmattan-SMS-Boat/smsImport
Source: https://github.com/merlin1991/Harmat...port/smsIm.cpp

edit: Thanks to a tip from jbrooks it works now perfectly, no more segfaults. The new binary is available at the link above.
