|

With a new kde 4.10.0 I have this problem. Do you think is related to Gentoo or to KDE - I do not know where to report.
Code: | Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.00
Qt Version: 4.8.4
Operating System: Linux 3.7.6-gentoo x86_64 |
Code: | Application: Nepomuk Service Stub (nepomukservicestub), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Hi, I have added a temporary debug USE flag to nepomuk-core package, but output is still with "??".
Code: | $ equery u nepomuk-core
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for kde-base/nepomuk-core-4.10.0:
U I
- + debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see http://www.gentoo.org/proj/en/qa/backtraces.xml

Same segfault problem with nepomuk-4.10.0... Xyva, did you make a bugreport to KDE bugzilla already? _________________ "Trust me, I know what I'm doing!"

I guess this should be fixed by nepomuk-core-4.10.0-r1. |

I've got the same problem but I'm running Kubuntu 12.10, KDE 4.10. Looks like it's a KDE issue. |

Another advantage of compiling a package with debug info is that it makes the KDE krashdialog happy because then the crash report contains useful developer info too. |

^ Please follow these instructions to get meaningful backtraces. |
So what should I do?
Add -ggdb flag to CFLAGS
and add splitdebug to FEATURE in /etc/make.conf?
What else, should I recompile this package or all system?
What about debug USE flag? Should I enable this flag as well? Or maybe in case I am not using those flags above? |
