Comment 2 for bug 641302

Which version of Stellarium is that? 0.10.4 that is in the default repositories, or 0.10.5 from the PPA or the Debian repositories?

The log file is called "log.txt" and can be found in ~/.stellarium (the hidden subdirectory ".stellarium" of your home directory). You don't need to copy the log's contents, you can simply attach the file. (Use the "Add attachment or patch" link below.)
