The "DebuggingKDE" page has been changed by penalvch:

Comment:
Added support note on missing -dbg symbols when using reporting assistant.

   1. Crasher bugs - Log files from the crash incident are required to track down these.
  
  Some possible problems with bug reports include:
-  1. Hardware specific bugs - The developers may not have access to the hardware that triggers this bug. Certain log files and command outputs can help.  For KDE, this can be relevant e.g. in configuration dialogs.

+ Applications by default on Kubuntu will generate useless backtraces when they crash. To get useful backtraces, all debugging symbols for the application need to be installed.
+ 
+ When utilizing the Crash Reporting Assitant, this should give you the opportunity to install the necessary debug symbol packages. However, if one gets a window noting the following example: {{{
+ Missing debug information packages
+ The packages containing debug information for the following application and libraries are missing:

- == Packages with Debugging Symbols ==
- Applications as installed by default on Kubuntu will generate useless backtraces when they crash.  To get useful backtraces, you need to install the package with debugging symbols for the application.
  
- Every official KDE module has an additional package in the repository, suffixed with -dbg. Always install kdelibs-dbg, because all KDE applications use kdelibs. Then you should install a -dbg package for the application which crashed. For example if KOrganizer crashed you should install kdepim-dbg as well.  See [[DebuggingKDE#head-700ed3979b895dbb8fa78c9516ed89c536bea345|choosing the right package]] to help figure out what module an application is in.  For KDE4 on Hardy, these will be -dbg-kde4.

-  * Unconfirmed ("''New''") bugs are a priority.  An unconfirmed bug isn't of much use to a developer or to the reporter.  It's a waste of developers' time to try to figure out if things are even real bugs, so that's our job.  Do your best to reproduce bugs so that you can confirm them.

-  * Bug reports often lack essential information required to fix them or to find out if they are already fixed.  This can range from basic information such as what release they are using or even what program the bug is in to slightly more complex things like stack traces for crashes.  Ask the reporter for any missing information.  Be clear and polite.  When you ask questions, mark the bug status as "''Incomplete''" until all the required information is provided.  If you can reproduce the bug, provide the information yourself and mark "Confirmed."

-  * Many bugs have already been fixed.  For older bugs that you cannot reproduce, ask if the reporter is sill having the problem.
