Please report all bugs along any relevant information to Wine Bugzilla. Please, search the Bugzilla database to check whether your problem is already reported. If it is already reported please add any relevant information to the original bug report.
Some simple advice on making your bug report more useful (and thus more likely to get answered and fixed):
Post as much relevant information as possible.
This means we need more information than a simple "MS Word crashes whenever I run it. Do you know why?". Include at least the following information:
Which version of Wine you're using (run wine --version)
The name of the Operating system you're using, what distribution (if any), and what version (e.g. Linux Red Hat 7.2).
Which compiler and version (run gcc -v). If you didn't compile Wine then the name of the package and where you got it from.
The name of the program you're trying to run, its version number, and a URL for where the program can be obtained (if available).
The exact command line you used to start Wine (e.g. wine "C:\Program Files\Test\program.exe").
If there is a crash dialog on the screen acknowledge it so ensure all information is printed to the terminal.
Useful terminal output contains a backtrace with debug symbols, see the Backtraces wiki entry.
Create an attachment with full terminal output in a text file.
cd ~/.wine/drive_c/Games/Tron wine tron.exe &> log.txt
The exact steps required to reproduce the bug.
Any other information you think may be relevant or helpful, such as X server version in case of X problems, libc version etc.
You may be asked to re-run the program using a custom
WINEBUGenvironment variable value, e.g.
WINEDEBUG=+relay,+seh,+tid wine sol.exe &> log.txt.
This will produce additional information which may include the cause for a crash or may be helpful in debugging the program. It also slows the execution of program. There are some cases where the bug seems to disappear when +relay is used. Please mention that in the bug report.
