FreeBSD 4.1 Mozilla 20010425xx Go to quote.yahoo.com. Type in WGAT and submit. Click on charts (OUCH!). Click on one day. Grab scrollbar and drag. I got this assertion (which may be hard to repeat if it depends on exactly what was damaged by the drag): Assertion: You can't draw an image with a 0 width or height! GDB backtrace attached. height is 0. One level up, in nsImageFrame::Paint, "inner" is this in unscaled coordinates: (gdb) p inner $2 = { x = 0, y = 319, width = 1680, height = 3 }

BTW, I also get these assertions (perhaps for other reasons; I haven't backtraced them, and I don't think I was dragging the scroll bar, though I may have been page up/down-ing) at planethalflife.com

pav wants to investigate this before deciding which milestone. till then, this can wait in 0.9.2 bucket

using today's CVS on GNU/Linux: When I load http://www.advalvas.be I can get the assertion error too. It does'nt happen all the time, and sometimes I need to scroll up and down, but, it isn't really hard to reproduce. The debug output: ###!!! ASSERTION: You can't draw an image with a 0 width or height!: 'aSWidth > 0 && aDWidth > 0 && aSHeight > 0 && aDHeight > 0', file nsImageGTK.cpp, line 536 ###!!! Break: at file nsImageGTK.cpp, line 536

I get these assertions all over the web nowadays. I have to add a condition to my breakpoints so that I can run reasonably.

I have created a very small testcase, but I wasn't able to attach it. If someone is, please do it for me. Using the test, the assertion pops up each time the animated gif changes. http://users.skynet.be/www/todo/assertion.tgz (please attach it) I hope this makes it a lot easier to debug. (using latest CVS version on GNU/Linux i386)
