@sudhirkhanger Are you sure your backtrace is related to what @Germano0 reported? Your trace looks similar to #3656 - are you using Qt 5.5.0? Can you try a 2.0.0 nightly (https://build.opensuse.org/package/show/isv:ownCloud:community:nightly/owncloud-client)? |
|
I had the same message in the ABRT. Yes, I am on Qt 5.5.0. I can't even start ownCloud client for me to trigger a crash. It crashes on start. I will see about trying the nightly build. |
|
@sudhirkhanger btw, always good to use |
|
how can I start owncloud in debug mode to retrieve logs? |
|
@Germano0 Similar to above: |
|
@Germano0 Actually, you can also consider using 2.0rc2 |

|
We think we have a workaround for this in 2.0.0 (nightly or presumably rc2), a test would be appreciated! :) |

@ckamm is there a Fedora package available for 2.0.0? I can't find it |

$ owncloud --version |
|
@Germano0 Thanks, we are looking into it @sudhirkhanger Can you confirm the crash even with 2.0.0rc2 like @Germano0 ? |
|
Yes, I am able to reproduce the crash with [sudhir@fedora ~]$ gdb owncloud

@ckamm Could you please explain ReadyToTest label? How would I test? Using nightly repo? Or will I have to build it from the source? |
|
@sudhirkhanger I removed readytotest because we don't yet have a workaround to the Qt 5.5.0 issue. |
I am experiencing several crashes of owncloud-client-1.8.4-2.1.x86_64 on Fedora 22
