I also try to rewrite everything to be sure there was no weird character during the copy paste. I wrote: Metacello new githubUser: 'dalehenrich' project: 'metacello-work' commitish: 'master' path: 'repository'; baseline: 'Metacello'; get. Metacello new githubUser: 'dalehenrich' project: 'metacello-work' commitish: 'master' path: 'repository'; baseline: 'Metacello'; onConflict: [ :e | e allow ]; load But I got the same. Apparently there is a problem during the fetching of the baseline. In the Transcript I got: ...RETRY->BaselineOfMetacello ...RETRY ...RETRY I also deleted the github-cache before launching the command. Here is a screen to help you a little: http://puu.sh/q67ok/74e233309c.png I did not try on another OS (Windows 7 here), but I can try tomorrow. BTW, this is not related but in pharo 6, the github-cache/ should not be located in the image directory but in `SystemResolver userLocalDirectory` instead. This is a directory created by Esteban to reduce the noise created by the multiple files. Is it Metacello that create this folder?

You can not use stdout to print when doing image shutdown and restart, because all file streams will be closed during the shutdown (see session manager). If you want to use stdout to print log messages (right after image startup), you need to make sure that the stdout/err stream are already recreated.

Re: [Pharo-users] Spec, Icons in subclasses of ComposableModel

by Peter UhnÃ¡k

In that case it should be either self iconNamed: #smallBackIcon or #smallBackIcon asIcon that is â to avoid directly asking global singletons. This is similar to Theme, where one should not always ask Smalltalk ui theme, but instead have a single reference to it and ask "self theme". As for which one of the two would be better in this situation, I don't know. In general I would prefer the latter, but if there was a Spec-way added, then it should be used â it would make it easier to switch icons just for Spec in the future if such need would arise. Also thanks for all the Spec fixes, this is really important!
