gammu dies while issuing the following command (this should export entry
1 from the backup file as VCARD under output/1.vcf):
$ gammu savefile VCARD21 output/1.vcf backup-2008-01-27 ME 1
Segmentation fault
In my example the target directory (output/) does not exist. Gammu does
not check if the fopen() of the resulting file was successful. It just
does a fwrite() which may (as in my case) segfault.
Patch which checks the return value of fopen() appended.
Best regards from Erlangen/Germany!
