I tried similar code with python and it, too exhibited the same problem. Edit: Torsten Schoenfeld suggested the problem could be missing or incorrect annotations in gtk+.... Trying the perl scripts on Linux Mint (somewhat newer version but not the lastest) also was problematic. When running them on Arch, with all the software at or above the versions you have, the program performed without these problems. So I've concluded that it is, indeed, an issue with older software. I am satisfied to call the issue solved, but it would be nice to know just what was going on. I've tried several things, including specifying the text_column for the autocompletion, on each pass (If I didn't mention it, this was a ListStore for an autocompletion) and this didn't help.
