r5785, r5772 Crashing when Power-tunnel destoyed (Linux, x86_64)

[Wheart]

Hi!
I wasn't here for few years, but now I have some time to play Simutrans

Following steps guide to crash:
1. Make some power line with power-tunnel in the middle
1a. Check maintenance cost for power line and power tunnel - not necessary 
2. Remove line (with "Remove power lines" tool) - tunnel terminals and tunnel remain, but without power line inside...
3. Destroy one of terminals with "Destroy/Remove" tool - game crashes.

Observations: "removed" tunnel with terminals don't make connection (no power line inside of the tunnel, only terminals remain).
If terminal of an existing power tunnel was demolished using "Destroy/Remove" tool - tunnel is destroyed in a proper way.

About environment:
- Ubuntu 12.04 LTS x86_64
- Simutrans compiled from source (with native, 64bit libraries)
- gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)
- pak64, 111.3 from sf (not CVS/SVN)
