Bug#1136020: merkaartor: Merkaartor crashes attempting to download map data

[Neil Williams]

Package: merkaartor
Version: 0.20.0+ds-3+b1
Severity: grave
Justification: renders package unusable
X-Debbugs-Cc: linux at codehelp.co.uk

Launching merkaartor shows the main window but clicking Download
causes the app to immediately crash. Without map data, merkaartor
has no purpose.

I have also been able to reproduce this in stable.

The seg fault appears to be in OSMServer.cpp - 
Download failed: Invalid argument; 
So I'm suspecting the program is too old to use
the current OSM API. 
(The release is 2 yrs old and no recent commits upstream.)
