Package: racket Version: 7.1+dfsg1-1 Severity: normal Dear Maintainer,
In a recent version of Racket, the "Install Package" under "File" menu doesn't work and reports an internal error: cadr: contract violation expected: (cons/c any/c pair?) given: #f context...: /usr/share/racket/pkgs/gui-pkg-manager-lib/pkg/gui/private/by- source.rkt:534:4: adjust-deps method in by-source-panel% /usr/share/racket/pkgs/gui-pkg-manager-lib/pkg/gui/private/by- source.rkt:422:4: adjust-all method in by-source-panel% /usr/share/racket/collects/racket/private/class-internal.rkt:3554:0: continue-make-object /usr/share/racket/collects/racket/private/class-internal.rkt:3508:0: do- make-object /usr/share/racket/pkgs/gui-pkg-manager-lib/pkg/gui.rkt:44:0: make-pkg- installer8 /usr/share/racket/collects/racket/contract/private/arrow-val-first.rkt:428:3 /usr/share/racket/pkgs/gui-lib/mred/private/mrmenu.rkt:250:14: command method in basic-selectable-menu-item% /usr/share/racket/collects/racket/private/more-scheme.rkt:148:2: call-with- break-parameterization /usr/share/racket/collects/racket/private/more-scheme.rkt:265:2: call-with- exception-handler /usr/share/racket/pkgs/gui-lib/mred/private/wx/common/queue.rkt:430:6 /usr/share/racket/pkgs/gui-lib/mred/private/wx/common/queue.rkt:481:32 /usr/share/racket/pkgs/gui-lib/mred/private/wx/common/queue.rkt:629:3 Since I and many others are relying on this function (installing a package) for learning purposes, this problem may render Racket effectively unusable for these people. I hope you can consider fixing this problem. Thank you very much!
