can't open .vnc file anymore after upgrading ubuntu from 11.10 to 12.04

[JZ]

This command "vinagre -f -F Documents/cyclsvl10.vnc" stopped working after upgrading ubuntu from 11.10 to 12.04.

Got error message box: "An error occurred".

Status changed to 'Confirmed' because the bug affects multiple users.

There seems to be a bug in 3.4.2:

vinagre-utils.c

void vinagre_utils_show_error_dialog (const gchar* title, const gchar* message, GtkWindow* parent) {
 Block1Data* _data1_;
 const gchar* _tmp0_;
 GtkWindow* _tmp2_;
 const gchar* _tmp3_;
 GtkMessageDialog* _tmp4_;
 GtkMessageDialog* _tmp5_;
 const gchar* _tmp6_;
 GtkMessageDialog* _tmp9_;
 GtkMessageDialog* _tmp10_;
 _data1_ = g_slice_new0 (Block1Data);
 _data1_->_ref_count_ = 1;
 _tmp0_ = title;
 if (_tmp0_ != NULL) { <<<<<<==========
  const gchar* _tmp1_ = NULL;
  _tmp1_ = _ ("An error occurred");
  title = _tmp1_;
 }
 _tmp2_ = parent;
 _tmp3_ = title;
...

Should the if condition be "==" instead of "!="?
   if (_tmp0_ == NULL) {

After a gdb session, it turns out all keywords in .vnc file must be capitalized!

And function vinagre_connection_new_from_file() doesn't show the error message.

Even after capitalization and using the config above I still get the error.
