I have update FreeBSD's gpa port to version 0.7.4. This problem seems to
persist, however. Tests over here showed the following:

• Encrypting one file for one recipient works (multiple times).
• Encrypting two files for one recipient works, too, but prints a warning: "gpa in free(): warning: chunk is already free"
• Encrypting one or more files for two recipients results in the process eating 100% CPU time right after pressing OK. A progress window is not displayed. I sent the process a SIGABRT and acquired a backtrace with gdb:
