There's a fatal problem in the code. No memory is allocated to delimiter, which causes the segmentation faults. (But it does indeed at least try to detect the delimiter despite earlier comments, perhaps it was added to version 0.2?) By happy coincidence it sometimes works, though . The fix is simple, though, I put the patch here: http://modeemi.fi/~flux/software/mae...iter-fix.patch . A compiled binary (only the binary!) is at http://modeemi.fi/~flux/software/maemo/smsimporter (..until I remove it). Thanks for this very useful piece of software!
