I was working with changesets (manipulating them), then unexpectably, i got an error, and image hangs and starts consuming 100% CPU. I attempted to interrupt it - it shows a debugger, but still unresponsible.. This is a tail of PharoDebug.log: THERE_BE_DRAGONS_HERE Error: There is no free space in this set! 19 March 2010 10:37:13 am VM: Win32 - IX86 - NT - Squeak3.10.2 of '5 June 2008' [latest update: #7179] Image: PharoCore1.1ALPHA [Latest update: #11112] WeakIdentityKeyDictionary(Object)>>error: Receiver: a WeakIdentityKeyDictionary(a ChangeList->an IdentityDictionary(#getCompletionController->...etc... Arguments and temporary variables: Before that , i were able to fileout the changeset (see attached file) but then, when i tried to file it in from a file browser i got MessageNotUnderstood: receiver of "methodsFor:stamp:" is nil and again, unable to continue working and had to close image, because it unresponsive. What is interesting , that if i clicking 'changes' in a file browser, and then select everything and file it in, no errors happen and everything works just fine. But if i doing 'install' without looking at changeset details, i got the above error. -- Best regards, Igor Stasenko AKA sig.
