Reporting a Bug

Bug Tracker

For reporting any kind of bugs, use the GitHub issue tracker. Please take a look at other submitted bugs before opening a new item as someone else might have reported the same bug.

Reporting Bugs with gdb

If you are using LMMS and encounter a segmentation fault (crash), please include a full backtrace:

gdb /usr/bin/lmms
r

Then attempt to replicate the crash. Once LMMS crashes:

thread apply all backtrace

The output of this command is interesting for us! Please either report it to the issue tracker or email it to the mailing list.

How to Report Bugs without GDB

$ ulimit -l unlimited
$ lmms

Now when LMMS crashes, there will be a file called "core" in your working directory. The file may be large enough to be worth zipping.
