Raven panics when using juju errors

[j-fuentes]

I am using juju errors in my project and raven-go does not like them.

This example uses standard Go errors:

package main

import (
    "errors"
    "fmt"
    "os"

    "github.com/getsentry/raven-go"
    // "github.com/juju/errors"
)

func main() {
    client, err := raven.New(os.Getenv("SENTRY_DSN"))
    if err != nil {
        panic(err)
    }

    e := errors.New("test")
    s := client.CaptureError(e, nil)
    fmt.Println(s)
}

And it works:

$ go run .
39f60ebda4a946ebb7a2d5d2278f1d2e

However, if I try to use juju errors:

package main

import (
    // "errors"
    "fmt"
    "os"

    "github.com/getsentry/raven-go"
    "github.com/juju/errors"
)

func main() {
    client, err := raven.New(os.Getenv("SENTRY_DSN"))
    if err != nil {
        panic(err)
    }

    e := errors.New("test")
    s := client.CaptureError(e, nil)
    fmt.Println(s)
}

CaptureError panics:

$  go run .
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x727936]

goroutine 1 [running]:

Which version of raven-go? The line numbers in your stack trace don’t line up to master, so kinda hard to see what’s going on here.

oh sorry, I forgot to mention that. I have updated to the current master and patched the initial comment with the output.

• go version go1.12
• raven-go commit: 919484f041ea21e7e27be291cee1d6af7bc98864
