I am working on an App today and was able to debug it. Suddenly, I cannot use breakpoints without Xcode 5.1 crashing. It will stop at the breakpoint, it looks like it is trying to display local variables in the lower left window, and then it crashes.
This is a crash report:

ProductBuildVersion: 5B130a
Assertion failed: (!isNull() && "Cannot retrieve a NULL type pointer"), function getCommonPtr, file /SourceCache/lldb/lldb-310.2.36/llvm/tools/clang/include/clang/AST/Type.h, line 547.
(I can provide the rest of the report on what streams do, if useful).
I set breakpoints in different files and places in the code. I can use breakpoints in some places, but most breakpoints cause failures.
I scanned several SO pages with no luck. Among other things, I tried to remove all breakpoints and just add 1 back. I deleted and restored the schemes.
Any ideas?
I updated to 5.1.1. and the problem still exists:
