They can mean crap stored in the tree model, or perhaps they are harmless (normally I do not see treeviews produce these). In any case they do not say anything about the conversion problem (they say the test program is probably not very minimal though). If no *different* errors are printed first, then we have not found anything. Simple things that can be tried next: - if the numbers are normal, i.e. supported by underlying strtod(), try to use it directly -- be careful with the locale in this case - copy g_ascii_strtod() from the latest glib/strfuncs.c, paste to your code and use this copy to see whether it makes any difference Still, the randomness indicates a nasty bug in your program. I suppose if you make a minimal program that just reads the data, the problem goes away.
