Sigsev when trying to merge .kv file with no data #211

Closed goran-cliqz closed 7 years ago

goran-cliqz commented 7 years ago

If you add a .kv file with no entries in it and try to merge it, keyvi will fail with sigsev. Reproduce with the attached script. mergeSigsegv.txt

Good catch!

Somehow we always miss this case, e.g. there should be unit test for this.
