[gcmd-dev] Bug 351952 fix: crash when searching for locked files by content

[Mike Crash]

There is bug when searching for files by content and the file has no 
read permission. The file is found (list permission is set in 
directory), but the content cannot be read. In file 
gnome-cmd-search-dialog.c in function content_matches on line 226 there 
is no check for NULL buffer returned from load_file.

The function should be:

/**
* Determinates if the content of a file matches an regexp
*
*/
static gboolean
content_matches (GnomeCmdFile *finfo, SearchData *data)
{
   static regmatch_t match;
   gint ret = REG_NOMATCH;
   gchar *buf = load_file (finfo);
   if (buf)
   {
       ret = regexec (data->content_regex, buf, 1, &match, 0);
       g_free (buf);
   }
   return (ret == 0);
}

Please update it, it will fix bug 351952 and maybe 399464 too.

Thx

Mike
