DOM error when opening popups!

DOM problems when using a popup on Mac OS X, firefox 2.0.0.1

I discovered it since my FireFox? is set to warn about every error

Appears to be a minor error, but with a possible DOM error... who knows...

[Exception... "'Permission denied to get property XULElement.columns' when calling method: [nsIDOMXULTreeElement::columns]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "JS frame :: http://xinha.raimundmeyer.de/latest/popups/popup.js :: dlg_init :: line 38" data: no]

And also in the 'Extended settings' popup in the demo [Exception... "'Permission denied to get property XULElement.columns' when calling method: [nsIDOMXULTreeElement::columns]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "JS frame :: http://xinha.raimundmeyer.de/latest/popups/popup.js :: dlg_init :: line 53" data: no] popup.js (line 53) anonymousXinhaCore.js (line 3384) anonymousXinhaCore.js (line 3379) anonymousXinhaCore.js (line 3397) anonymous

WFM in latest nightly with FF 1.5

Poster can you please test in the latest nightly and tell which popup you were trying to open.

Tested with MacOS X 10.3/ FF2, no probs

I know these error messages. They pop up here and there, but I'm too little a Mozilla expert to know why :(

I think nevertheless this can be ignored and closed

no further response, seems not to happening too often, if still
