Incompatibility with IMCE (via WYSIWYG, IMCE Wysiwyg bridge)

Let's have content type called "page" having:
- textarea with input filter that uses CKEditor with IMCE support (modules: IMCE, WYSIWYG, IMCE Wysiwyg bridge)
- filefield (CCK) with set up and enabled file alias (modules File Aliases)

Problem occurs when image is added via IMCE to textarea: while added, proper path to image is preserved, after saving/updating the node path is being changed to something between "alias" and proper path, making it totally wrong and messy (even changing file name!). Example"

Doesn't matter if any file has been added to that node or not; alias for file is being proceed for images (uploaded file or browsed from server) added to other field (textarea) in this certain content type.

Alias:
"my_files/[filefield-onlyname-original].[filefield-extension-original]"

Proper path to image:
"mysite/sites/default/files/EXAMPLEimg.img"

Path after saving node:
"mysite/sites/my_files/.XAMPLEimg.img"
