#844 closed defect/bug (Incomplete/Missing infos)
CPU trash when "Lock on road" is disabled

Description
I'm running Navit SVN 4445 on the OpenMoko FreeRunner with Debian Sid.
Whenever I switch off the "Lock on road" option, the CPU usage raises from 35% to above 90%, then the program becomes unusable. If I switch again to Lock on road (eventually before systm trashing), the CPU usage returns to normal.
May be this issue is related to #422.
The problem exists also on my netbook (Debian Squeeze), where CPU usage raises from 1% to 50%. Here the problem is obviously less noticeable.
Let me know if I can help with more help. I can recompile Navit by myself.

Need more informations as I never witnessed this myself, including testing on a raspberry pi. Please reopen if you can provide more details.
Thinking about it, this also happens to me. I can't provide any numbers as I've never looked too closely (I'm on a netbook too, so as mentioned the problem is less noticeable), but will check and update.
This issue is almost definitely the same as #422 - tracking (in xml) == lock on road (in GUI) as far as I'm aware.
