Possible solutions for IDE Internal Error in Kylix 2.

Question:

Why am I getting the an IDE Internal Error when loading Kylix?

Answer: Here are some suggestions

If it is a conflict with the QT library paths you can try entering the following in a terminal window (command prompt):
$export LD_LIBRARY_PATH=
$export LTDL_LIBRARY_PATH=
$startkylix 
If it is not a QT conflict, then another possibility for Redhat 7.1 is to try running XConfigurator as root from a term window. For other distributions this may or may not work. It is possible that this is a problem with XFree86 V4.0.3 so you can try upgrading to XFree86 V4.1 or downgrading to V3.3.6, or just comment the pex5 line in your /etc/X11/XF86Config (or XF86Config-4) and restart X:
Section "Module"
        Load    "xtt"
        Load    "ddc"
        Load    "GLcore"
        Load    "dbe"
        Load    "dri"
        Load    "extmod"
        Load    "glx"
#        Load    "pex5"
        Load    "record"
        Load    "xie"
