dragotin commented 10 years ago

hm, the file name is "1". My first suspicion was that conversion from QString("1") to QVariant was somehow failing. But that was obviously not the case.

dragotin commented 10 years ago

is that reproduceable?

moscicki commented 10 years ago

I think the filename is rather starting with lowecase "L" -- it's "linux-master/..."

I am not sure I can reproduce it at will but I have seen the client crashing already few times. When I have more backtraces I will append to this ticket.

moscicki commented 10 years ago

I think it is pretty much reproducible -- same problem. It crashed overnight without much activity from me.

Could you please post the output of rpm -qa | grep sqlite here? Maybe this is caused by an bug in the sqlite3 driver?

moscicki commented 10 years ago

I also have an impression that on redhat 6 some dependencies must be wrong or maybe some internal csync code out-of-date. I see update detection problems which I never see repeating same tests on ubuntu.

Could you please check if all internal and external dependencies for 1.6 client on rh6 are correct?

cdamken commented 10 years ago

@lmaestro @rperezb @jnweiger Could you help me here?

luciamaestro commented 10 years ago

@moscicki Is still happening in 1.6.2 version? @cdamken how can I help?

moscicki commented 10 years ago

Hi,

I did not see this problem lately. My owncloud-client rpm version is 1.6.2-6.1

The sqlite dependencies on my OS seem to be the same as I previously reported for 1.6.0.

So I guess the crash was caused not by sqllite drivers but some bug in the owncloud client.

I think you may close this for now. I will reopen if this reappears.

dragotin commented 10 years ago

Thanks @moscicki for letting us know.

cdamken commented 10 years ago

@lmaestro Thanks, now look fine :+1:
