[mkgmap-dev] Creating defect tiles.

Hi, I'm using mkgmap very often and meanwhile it's working really good, but I found something, that some img files are broken. After integrating it into Mapsource, MS is crashing with an error xxxxxxxxxx.img has an broken record. How can I help you to find the problem? What do you nedd to find this issue? Error message, img file, my mkgmap commandline options. Something else? May I send this to the mailinglist? Regards, Marco
