It looks like a bug, either in glibmm or in glib.
A small but complete and compilable test program would be appreciated.
Which version of glibmm and glib do you use? Do you use Windows or a
Linux distribution or what? File names with spaces are more common in
Windows than in other OSes, I think.

I am not fully sure if this is a bug or I am using the library
incorrectly.
vector<string> fileNames;
Glib::RefPtr<Gio::FileEnumerator> files =
this->dataSourceDir->enumerate_children(); // dataSourceDir is type:
Glib::RefPtr<Gio::File>
Glib::RefPtr<Gio::FileInfo> file = files->next_file();
string filesName;
while(file)
{
filesName = file->get_name();
if(hasEnding(filesName, ".data"))
{
fileNames.push_back(filesName);
}
file = files->next_file();
}
This code works correctly when enumerating over a list of files in a
folder when none of the files contains a space. However if any file
contains a space then an exception is thrown either at: filesName =
file->get_name(); if the file is not the last in the directory or when
the function returns if it is the last in the directory.
The debugger shows the issue to be around a HeapFree class in the
free.c header.
I am using gtkmm-2.4 downloaded and installed from the website.
Thanks in advance for your help,
Regards.
