--- Comment #1 from Tom Hardy <rhardy702 at gmail.com> ---
This appears to be the bug affecting me the most at the moment--an ever
increasing number of corrupted or misplaced tiles under Marble 1.5, KDE 4.10.5,
until I do some cleanup, and then It starts again.

My use case is a Linux laptop mounted in a car,  logging into a large number of
WiFi hotspots, very likely for a few seconds at a time as I drive by.

Corrupted tiles are evidenced by Marble using a fuzzy tile from another zoom
level.  When I have bothered to dig one out, it was indeed labeled as corrupted
by an image viewer.  I never thought to see if it was a web page of something.

Misplaced tiles show fine, but are displaced from an adjacent position or more
than a  kilometer away.  They can be from a different zoom level.  I won't try
to explain but I move a lot, and perhaps change zoom levels for one reason or
another.

It would be an improvement if automatic downloading could be disabled.

Alternatively, couldn't you use use something like wget or libcurl for file
downloading?  I would think you shouldn't need to completely reinvent the
wheel.
