+Summary: Using of Rsvg.Handle.SizeCallback causes permanent 99% cpu usage and memory exhaustion on WindowsXP
+
+I'm sorry, but there is no Rsvg compoment, so I choosed corlib, please
+correct it.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+If I use Rsvg.Handle.SizeCallback to set a custom size then mono uses 99%
+cpu time and memory allocation grows to exhaustion. 
+The bug seems to be valid only for windows os, because on FreeBSD it works
+well. Methods like FromFileAtSize works well on booth os.
+
+Steps to reproduce the problem:
+1. compile attached source rsvg-test.cs
+2. run it to see that test works ;)
+3. uncomment a marked line
+4. recompile
+5. run, try resize window and watch memory and cpu usage
+
+Actual Results:
+
+Mono permanently uses 99 to 100% of cpu and causes memory exhaustion, after
+some time.
+
+Expected Results:
+
+No memory exhaustion and permanent 99 to 100% cpu usage.
+
+
+How often does this happen? 
+
+often
