#52 Segfault when opening show window on linux

[Kyle Barlow]

The program segfaults whenever I attempt to create a new show or open an existing show. The fault occurs within the tbarbase.h wxWidgets library file which is called at line 223 in calchart file basic_ui.cpp.

I haven't quite familiarized myself enough yet with the project or wxWidgets to track down the bug, but am working on it. Any guidance would be much appreciated.
