Your X server should never barf on a Pixmap of depth 1.
You need to include more information and a code sample.
How are you using the Pixmap?  Are you using XCopyArea?
Are you using XCopyPlanes?  Are you just using a widget?

But in answer to your question use XCreatePixmapFromBitmapData.
It should return you a multi-plane pixmap using bitmap data.

Here is the general rule :

	Using XCopyArea, the depths have to match.
	Using XCopyPlane, the source should probably be depth 1.
		XCopyPlane uses the foreground and background as
		replacements for 1 and 0 respectively.

The Athena label widget uses XCopyPlane for 1-bit pixmaps, and
XCopyArea for multi-plane pixmaps (a small hack, but works most of the time).
