Hi,
I have just tried to move on to v4.8 and I have encountered an error, on both
precompiled binaries for OSX 10.6 64bit (running on OSX 10.6.8) and on OpenSuse
Linux 64bit (where Sage was compiled from sources, which went OK).
The error is as following: on any worksheet, if a click "evaluate" under a
cell, the web browser sends the request to the server, and it waits for it, but
it never receives one. Instead Sage outputs the same error several times
(appended in the end). If I "save & close" and then reopen the worksheet I now
see the result of "evaluate" under that cell which tells me the issue is in
server's response to requests.
Sage error output (identical on pre-build binaries for OSX and on compiled from
source sage on Suse Linux), repeated several times for one request:
