From 47b9134f75dd6e567f5670d0038420926d043342 Mon Sep 17 00:00:00 2001

Subject: Change the logic for preserve the mime type at reading and saving files

Open the text files in plain/text format, save the new file like .odt files
and preserve the mime type in all the cases but .doc files (abiword saves them like .rtf)
Related to tickets SL #2127, OLPC #8972, OLPC #5291 and OLPC #1925
