Dotaz: Opera pada se seg faultem

[tomas]

Prosim o pomoc. Mam aktualni verzi opery a z niceho nic (alespon nemuzu na nic prijit) mi zacla padat po 1 minute. Uz nevim co s tim... Zkousel jsem stavajici verzi i beta Opera 11. Stejny vysledek. Co s tim dal, deje se to i po vycisteni profilu?

 

 

- vycistil jsem profil

bio@dell-xps:|~$ mv .opera .opera_crash

- opera link disabled

- all extensions disabled

 

start opera.. a po jedne minute:

bio@dell-xps:|~$ opera

opera: Activated running instance

Segmentation fault

bio@dell-xps:|~$

Why this version is spying on me (doing wireless scans; I see ioctl SIOCGIWSCAN on linux x86_64 version being called) even if I disabled geolocation in preferences? (disabling in opera:config also didn't help)

It shouldn't need to do any wifi scans then.

How I noticed that? Well, UI freezes sometimes in this snapshot and opera is doing scans at that moment ;/
