Profile tool fails to close if legend text contains non-latin letters

[marisn]

Steps to reproduce:

• Start wx profile tool
• Profile options -> Profile plot settings
• Change "Transsect segment marker" legend text to "āšņļ"
• As there is no OK button (WTF? Designed for Mac users?!?), click "Save" to close this window
• KaBOOM!
