Comment 11 for bug 579392

Can you please do a few things to check that this is the same bug?

Firstly, does the problem go away eventually? This bug would leave empty tiles no matter how many times you restarted or waited.

Secondly, is there a 0-byte file on the device for the tile that has a problem? First find the offending tile's file name from opensatnav.org. Then try to find that file on the device.
If the tiles were stored on the SD card you can find them in the osn folder. If they're in internal memory they will be in the /data/data/org/opensatnav/files/ folder. If you find the 0 byte file then that confirms that the problem is still there.

Also, you need to be root to get into the /data/data folder. I just used terminal on the device, then checked the size using du.
