Hi, I installed galaxy completely from scratch: rm -rf galaxy-dist && hg clone https://bitbucket.org/galaxy/galaxy-dist/ I'm not a mercurial expert but I think I have changeset 8530:a4113cc1cb5e; at least that's the first entry in "hg log". Then started galaxy like this: cd galaxy-dist ./run.sh I went to http://localhost:8080 and tried to upload a file. I never saw the file in my history, and this is what printed out in the console after I clicked "Execute" on the "Upload File" page: galaxy.web.framework DEBUG 2013-01-23 13:56:11,573 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create galaxy.web.framework DEBUG 2013-01-23 13:56:11,573 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create galaxy.web.framework DEBUG 2013-01-23 13:56:11,573 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create galaxy.web.framework DEBUG 2013-01-23 13:56:11,573 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create galaxy.web.framework DEBUG 2013-01-23 13:56:11,573 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create galaxy.web.framework DEBUG 2013-01-23 13:56:11,573 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create galaxy.web.framework DEBUG 2013-01-23 13:56:11,573 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create galaxy.web.framework DEBUG 2013-01-23 13:56:11,574 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create galaxy.web.framework DEBUG 2013-01-23 13:56:11,574 Error: this request returned None from get_history(): http://localhost:8080/tool_runner/upload_async_create 127.0.0.1 - - [23/Jan/2013:13:56:11 -0700] "POST /tool_runner/upload_async_create HTTP/1.1" 500 - "http://localhost:8080/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.56 Safari/537.17" Debug at: http://localhost:8080/_debug/view/1358978130 127.0.0.1 - - [23/Jan/2013:13:56:11 -0700] "GET /tool_runner/upload_async_message HTTP/1.1" 200 - "http://localhost:8080/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.56 Safari/537.17" 127.0.0.1 - - [23/Jan/2013:13:56:11 -0700] "GET /history HTTP/1.1" 200 - "http://localhost:8080/tool_runner/upload_async_message" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.56 Safari/537.17" Hope someone can help.
