Description

When doing a save while playing, the game will crash. Further actions to load or save through the main menu, ALT-F2 or F9 in game, again will also crash the game as it appears look at the corrupted save and not like it. Access to these windows will no longer work until save file is deleted from savegame directory. Terminal output before the game dies is:

double free or corruption (top)
SIGNAL 6 caught, aborting

Trying to load said file will output the following:

Descent 3 Message(Error: Reading file </home/dangermouse/.wine/drive_c/Games/Descent3/savegame/saveg000>: error = Unexpected end of file
)

Crash appears on rendering thumbnail image of save game. #348 should solve game crash on double free. Another issue is game cannot correctly handle with corrupt savegames.

Confirming that #348 solves the game save problem. Opening #351 for the corrupted file load
